Matthew 5:27-30

Adultery in the Heart


Our Lord Jesus deals with all the issues of life in this profound sermon. Last time we looked at the moral Law regarding murder, and we pointed out that the act of murder takes place in the heart and essentially begins with anger. Now before us is the seventh commandment that speaks against committing the act of adultery of which the Pharisees rest assured that they were safe and secure. They were experts regarding the letter of the Law. But our Lord takes this commandment beyond the act and deals with the spirit of the Law which forbids lust in the heart. When it comes to prevention of committing this sin of adultery as far as the letter of the Law is concerned, the Roman Catholic Church’s teaching was to enforce the law of celibacy to the clergy. (Priests, Monks, Bishops, Nuns etc.)

Martyn Lloyd Jones comments, “Any teaching that makes us live an unnatural life is not New Testament holiness.” The apostle Paul would call this a doctrine of demons those who would “forbid marriage and advocate abstaining from foods, which God has created to be gratefully shared in by those who believe and know the truth.” (I Tim.4:3)
