The seventh of the Ten Commandments, which God spake in the long ago,   "Thou shalt not commit adultery" Exodus 20:14. This has always been   God's law. We are told in I John 3:4, that sin is the transgression of   God's law, therefore, to commit adultery is to transgress God's law, and   therefore, sin. Not only has God forbidden adultery, but the son of God   himself said, "Whoso looketh on a woman to lust after her, hath   committed adultery with her already in his heart" Matthew 5:28. If the   adulterous thought is sin, surely the adulterous act is sin. The Holy   Spirit through the inspired apostle has told us plainly that adultery is   a sin. Peter described some sinners of his day as having "eyes full of   adultery, that cannot cease from sin" II Peter 2:14. Paul warned the   Corinthians to "flee fornication" I Corinthians 6:18.

                         The seriousness of the sin of adultery can be seen in several ways.   Under the law of Moses the penalty was death by stoning. (Deuteronomy   22:21 ff, John 8:4,5). Again, the only ground that God gave for   divorcing one's mate was sexual immorality. He said, "Whosoever shall   put away his wife, saving for the cause of fornication, causeth her to   commit adultery. And whosoever marry her that is divorced, committeth   adultery" Matthew 5:32. But the seriousness of adultery is seen most   clearly in the eternal punishment of those who commit the sin. An   impenitent adulterer cannot go to heaven. Ephesians 5:5 says: " "No   whoremonger, no unclean person hath an inheritance in the Kingdom of   Christ and of God." And in Colossians 3:6, we are told that because   fornication, uncleanness, and inordinate affection, the wrath of God   comes on the children of disobedience.
