What does the Bible say about emotional affairs?

Bible Topic · WEB

The Bible teaches that sexual and romantic desires outside the covenant of marriage are sinful in heart as well as in outward action, calling believers to faithfulness, purity, repentance, and reliance on Christ. In Matthew 5:27-28, Jesus exposes lustful looking as adultery of the heart, while Matthew 5:32 upholds the seriousness of the marriage covenant. Hebrews 13:4 honors marriage and warns against sexual immorality. Scripture therefore calls us to flee tempting intimacy and to pursue wise, transparent boundaries, as 1 Corinthians 6:18 and 10:13 teach. Husbands and wives should cultivate honor, understanding, and marital devotion, as 1 Peter 3:7 and 1 Corinthians 7:1-40 encourage. For those who have sinned, 1 John 2:1-2 points to Christ, our righteous advocate and atoning sacrifice.
