Matthew 19:3–9: What Jesus Says About Divorce
Jesus answers a testing question about divorce by going behind the law to God's design from the beginning: marriage is God's joining of two into one flesh. The certificate of divorce was a concession to hard hearts, not a picture of what God intended.
Matthew 19:3–9: Is Divorce a Sin?
Jesus refuses to start with grounds for divorce and instead starts with God's making of male and female and the joining of two into one flesh. He names one exception, sexual immorality, and treats the Mosaic allowance as a concession to hard hearts rather than the original design.
