Scripture permits protecting life and restraining an attacker in some circumstances, but it forbids vengeance and requires necessity, proportionality, love of neighbor, respect for law, and a strong preference for escape and peace.

Christians should engage politics as citizens of God’s kingdom: seeking justice and neighbor-good, honoring lawful authority, resisting idolatry and evil, and refusing to identify Christ’s church with any party or nation.

The Bible does not address modern euthanasia by name, but it affirms God's authority over life and death, prohibits intentional killing, commands compassionate care, and permits refusing burdensome treatment. Deliberately causing death differs from allowing natural death while relieving suffering.

Christians may view some IVF treatments as morally permissible help for infertility, but decisions must protect embryonic human life, marital faithfulness, informed consent, health, justice, and conscience.

Scripture presents unborn human life as known by God and bearing human dignity, so Christians should protect life in the womb while showing truthful compassion to women, families, and those carrying grief or guilt.

The Bible consistently locates sexual union within the covenant marriage of man and woman and therefore does not affirm same-sex sexual relationships. Christians must state that conviction with humility, reject contempt and coercion, and honor every person's God-given dignity.

The Bible does not mention masturbation directly, so Christians should not invent a direct prohibition; they should evaluate it through Scripture’s teaching on lust, self-control, conscience, embodied holiness, and love.

A Christian should seek marriage with another Christian because marriage joins lives, worship, vocation, and household direction; a believer already married to an unbeliever should not pursue divorce merely for that reason.

Historic Christian interpretation understands sexual intercourse as belonging within marriage, the covenant union of husband and wife. Sex before marriage departs from that pattern, yet sexual sin is neither unforgivable nor a basis for shaming people.

The Bible does not name cigarettes or vaping, but its teaching about bodily stewardship, enslavement, sobriety, neighbor-love, and wise freedom strongly warns against nicotine use and its harms.

Scripture does not name every wager, but gambling commonly conflicts with wise stewardship, contentment, productive provision, self-control, and love of neighbor; addictive or harmful gambling must be abandoned.

The Bible does not name modern marijuana directly. Christians should evaluate it through sobriety, self-control, lawful authority, love of neighbor, health, conscience, and freedom from mastery. Intoxication for escape or pleasure conflicts with watchful discipleship.

The Bible does not call every use of alcohol sinful, but it plainly condemns drunkenness and requires wisdom, self-control, lawful conduct, and love for people endangered by our freedom.

Cremation is not identified as sin in Scripture. Burial has rich Christian symbolism, but God can raise the dead regardless of how a body returns to dust, so families may decide with faith, wisdom, and conscience.

Leviticus 19:28 prohibited Israel from cutting the body for the dead and making tattoo marks within a holiness code that opposed pagan mourning and worship practices. It does not by itself prove every modern tattoo is sinful, but motives, message, conscience, stewardship, and love still matter.
