Age-of-adulthood
Short answer: The Bible does not set a single age at which a person becomes an adult. 1 Corinthians 13:11 says, "When I was a child, I spoke as a child, I felt as a child, I thought as a child. Now that I have become a man, I have put away childish things." Paul is not legislating a birthday. He is describing a transition from childish speech, feeling, and thinking to mature speech, feeling, and thinking. Scripture elsewhere treats adulthood as a moral and spiritual reality: the ability to receive instruction, to exercise self-control, to take responsibility for one's own faith, and to stop being carried about by every wind of teaching. Cultures and governments may fix legal ages for marriage, military service, or contracts, and those laws are legitimate, but they are not the Bible's measure of maturity.
Paul is talking about love, not laws about age
1 Corinthians 13 sits in the middle of a letter about a divided, gifted, and immature church. The Corinthians prized impressive spiritual gifts and measured one another by them. Paul answers by showing a more excellent way, and he personifies love in a series of plain statements about patience, kindness, and endurance. Then he adds the line about childhood. He is illustrating something about the church's growth, not issuing a statute about when a young person may be considered grown.
Read in context, the childish things Paul put away are not toys or hobbies. They are the immature patterns he has just contrasted with love: envy, boasting, arrogance, rudeness, and the insistence on one's own way. A person can hold a job, marry, and pay taxes while still speaking and thinking like a child in these matters. That is why the passage cannot be reduced to a legal age. It is a mirror held up to the heart, and it asks whether our love has grown up.
This also means the passage is not a weapon against the young. Paul is not telling churches to dismiss young believers. In 1 Timothy 4:12 he tells Timothy, "Let no man despise your youth; but be an example to those who believe, in word, in your way of life, in love, in spirit, in faith, and in purity." Age and maturity are related but not identical, and Scripture honors the young who walk faithfully.
What the Bible does say about growing up
Scripture speaks of growth in two directions at once. There is the ordinary growth of a human being from infancy to adulthood, and there is the spiritual growth of a believer into Christlikeness. Luke 2:41-52 records the only inspired glimpse of Jesus between infancy and ministry. It closes by saying he grew in wisdom and stature, and in favor with God and men. Human development matters to God; it is not an accident to be rushed or despised.
At the same time, the New Testament repeatedly commands believers to grow up spiritually. Ephesians 4:14-15 warns against remaining children who are tossed back and forth and carried about with every wind of doctrine, by the trickery of men. The goal is maturity, and the means is truth spoken in love. Romans 12:2 adds that this maturity comes by the renewing of the mind, not by simply getting older. A person can age for decades and remain spiritually infantile.
So the Bible treats adulthood less as a date on a calendar and more as a direction of life. Are you learning to receive correction? Are you able to hold convictions without being blown around by every new teacher? Are you taking responsibility for your own walk with God rather than living off someone else's faith? These are the Bible's questions, and they apply to every age.
Training a child aims at adulthood, not perpetual childhood
Proverbs 22:6 says, "Train up a child in the way he should go, and when he is old he will not depart from it." The proverb pictures training with a destination in view. You do not train a child so that the child stays a child. You train a child so that the child becomes an adult who walks in that way. The goal of biblical nurture is not a permanent dependency on parents but a settled, personal faith that can stand on its own feet.
This is why parenting in Scripture is a long, patient project of handing over responsibility. A child learns to obey, then to choose, then to lead. A young person learns the reasons for the faith, not only its rules. Parents who understand this do not fear their children's questions or rush their children's independence. They aim at the day when the child can say with Paul, in effect, that childish things have been put away, and can do so with gratitude for the training that made it possible.
The proverb is often read as an absolute guarantee, and that is a misreading. It is a proverb, a general truth about the normal harvest of faithful training, not a mechanical promise that overrides a child's own will or God's freedom. Scripture elsewhere shows godly parents with wayward children and wayward parents with godly children. The proverb encourages faithful work; it does not bind God to a formula.
Age of accountability is not the same as age of adulthood
Many Christians speak of an age of accountability, the point at which a person becomes morally responsible before God. The phrase itself is not found in Scripture, and the Bible gives no number. What Scripture does teach is that all have sinned and that God is just and merciful in his judgments. Whatever we conclude about children who die young, we must conclude it with humility, because God has not told us everything we might wish to know.
It is a mistake, then, to merge the age of accountability with the age of adulthood and treat them as one birthday. A young person may come to genuine faith and repentance years before they are legally independent, and an older adult may live for decades without ever seriously turning to God. Spiritual responsibility and social adulthood are related but distinct, and confusing them produces either anxious children or complacent adults.
The practical upshot is that we should stop looking for a single number and start looking for the marks of maturity the New Testament actually describes. Faith that is personal, love that is patient, doctrine that is tested, and conduct that is self-controlled. These can appear early or late. They are the real evidence that someone has put away childish things.
Young believers are not exempt from serious discipleship
It is easy to treat youth as a waiting room, a season where real obedience is postponed until adulthood. Scripture does not permit that. Timothy was young, and Paul still commanded him to be an example in word, in way of life, in love, in spirit, in faith, and in purity. Nothing in that list is reserved for the middle-aged. A teenager can be a model of purity and faith, and churches should expect it and encourage it.
At the same time, churches should not crush the young with burdens that belong to adulthood. The New Testament's pattern is to give young believers real responsibility, real instruction, and real opportunities to serve, while surrounding them with older believers who model maturity. In a healthy congregation, the young are not sidelined and the old are not idolized. Each is called to grow, and each is called to help the other grow.
The broader culture pushes in the opposite direction, treating adolescence as an extended playground and adulthood as something to be delayed as long as possible. Christians can quietly resist that drift by honoring early faith, by discipling young people seriously, and by refusing to treat immaturity as normal for anyone, young or old. The call to put away childish things goes out to every age at once.
How to tell whether you have actually grown up
Since Scripture gives no single age, the honest question is whether the marks of maturity are present in your life. Paul's list in 1 Corinthians 13 gives us a workable test. Love is patient and kind. It does not envy, does not boast, is not proud, is not rude, is not self-seeking, is not easily angered, keeps no record of wrongs. If you want to know whether childish things have been put away, read that list slowly and let it search you.
A second test is teachability. Children resist correction and defend themselves; mature people receive correction and change. A third is stability in doctrine. Ephesians 4:14 describes the immature as tossed back and forth and carried about with every wind of doctrine. A grown-up believer has convictions that have been tested and can give a reason for the hope within them, as 1 Peter 3:15 says. A fourth is responsibility. Mature believers keep their word, provide for their households where they can, and serve others without needing to be managed.
None of these marks is automatic with age. They are the fruit of the Spirit working through the ordinary means of grace: Scripture, prayer, fellowship, and obedience over time. If you find yourself lacking, that is not a verdict on your age. It is an invitation to grow, and God is patient with those who are still learning to walk.
Why legal ages still matter even though the Bible gives none
Nothing in this article denies that societies need legal thresholds. Marriage, voting, military service, contracts, and criminal responsibility all require workable lines, and governments are within their rights to draw them. Romans 13 tells us to submit to governing authorities, and those laws serve real purposes. But we should be clear about what they are. They are civil arrangements, prudent and necessary, not divinely revealed ages of spiritual maturity.
Christians should therefore hold legal ages lightly while holding maturity seriously. A person may be legally adult and spiritually childish. Another may be legally a minor and spiritually discerning beyond their years. The church is called to recognize and nurture the second while gently challenging the first. That means giving young believers room to serve and speak where Scripture permits, and refusing to let older believers coast on their years.
The practical counsel is simple. Honor the law of the land where it speaks, and honor the law of love where it searches the heart. Those two do not conflict, because the law of the land was never meant to measure the soul. Only God's word does that, and it measures every age by the same standard, which is Christ himself.
Biblical fidelity check
What 1 Corinthians 13:11 establishes is that Paul moved from childish speech, feeling, and thinking to mature speech, feeling, and thinking, and that he deliberately put away childish things. It does not establish a chronological age for adulthood, does not define which specific behaviors count as childish, and does not command the church to treat any particular age as the threshold of responsibility. It is an illustration drawn from ordinary human development, used to press the Corinthians toward mature love.
A common misreading takes the verse as a template for cultural independence: as soon as someone reaches a certain age, they must move out, stop obeying their parents, and sever family ties in the name of maturity. That is not what Paul says. His contrast is between immature love and mature love, not between living at home and living elsewhere. Another misreading treats the verse as a reason to silence young believers entirely, but 1 Timothy 4:12 forbids exactly that. The passage calls for grown-up love in every season of life.

Frequently asked questions
Does the Bible give an age at which someone becomes an adult?
No. Scripture never names a single age for adulthood. It describes adulthood in moral and spiritual terms, such as putting away childish things, being renewed in the mind, and no longer being tossed about by every wind of doctrine. Legal ages for marriage, service, or contracts are legitimate civil arrangements, but they are not revealed in Scripture. Christians are free to respect those laws without treating them as divinely fixed thresholds of spiritual maturity.
What does Paul mean by childish things in 1 Corinthians 13:11?
In context, Paul is describing the immaturity he has just contrasted with love: envy, boasting, arrogance, rudeness, and self-seeking. He is not listing toys or hobbies. He says, as 1 Corinthians 13:11 puts it, that he spoke, felt, and thought as a child, and then put those childish ways away when he became a man. The childish things are immature patterns of relating to others, which can persist long past any legal age of adulthood.
Is the age of accountability the same as the age of adulthood?
No. The phrase age of accountability does not appear in Scripture, and the Bible gives no number for it. It refers to the point at which a person is morally responsible before God, which is a different question from when someone is socially or legally adult. Young people may come to genuine faith early, and older adults may remain spiritually immature for decades. Confusing the two categories produces confusion in both directions.
