What does the Bible say about emotional affair?

Bible Topic · WEB

The Bible teaches that romantic or intimate emotional attachment outside marriage is a matter of the heart that violates marital faithfulness and calls for repentance, truth, and wise boundaries. Jesus teaches in Matthew 5:27-28 that sinful desire begins within, while Jeremiah 17:9 warns that the heart can deceive us. Christians are called to flee sexual immorality, take captive ungodly thoughts, and walk in love and purity before God, as 1 Corinthians 6:18 and 2 Corinthians 10:5 teach. Confession to trusted believers, prayer, and accountability are fitting helps according to James 5:16. In Christ, temptation need not rule us, for God provides a way of escape and grace to restore those who turn to him.
