You have heard that it was said, ‘YOU SHALL NOT COMMIT ADULTERY' (Matt 5:27 NASB)
Here Jesus is going to adjust our understanding of sexual sin. The Bible is pretty clear about its prohibition of sexual intercourse outside of marriage. We can point at the early part of the Old Testament with the patriarchs and their myriad wives, and it could make you wonder what changed. But even from the beginning it was God’s intention for a man to have one wife.
Genesis 2 tells us that after God formed man, He fashioned woman for him, and intended that the man leave his father and mother and cleave to his wife.
but I say to you, that everyone who looks on a woman to lust for her has committed adultery with her already in his heart. (Matt 5:28 NASB)
You have heard that it has been said, there is no harm in looking, but I say unto you… Jesus gives us some serious instruction here. I hear this all the time. People, mostly men, talking about looking, but not touching, as if it is all on the up and up, but Jesus says when you look with a plan to lust, or as a result of lust, you have already done the deed in your heart.
Does this mean, since you are already guilty, you should go ahead? God forbid. Jesus was using this instruction not to say – well, you have already blown it, you might as well go for it, or as our culture might say it, follow your heart (boy there is some bad advise – see Jeremiah 17:9.)
Jesus’ point here was to expose our hearts to light. If there is lust in your heart, and you are living an outwardly clean and proper life, but lusting in secret, Jesus wants to you be free. He teaches here, that the heart that lusts is enslaved and keeping you from God’s best. [Tweet This]
Let me take this one more place. Paul asks a question of the people in Corinth:
Or do you not know that the one who joins himself to a harlot is one body with her? For He says, “THE TWO WILL BECOME ONE FLESH. (1 Corinthians 6:16 NASB)
Follow me now – Jesus says looking is the same as doing and Paul says when you take a harlot, you become one with her. This idea of “two become one” is not something that happens over 20 years of marriage, but it is a spiritual transaction that takes place when you engage in sex.
That is why the prohibition for adultery and fornication are brought forward to the New Testament Church. Sex outside of the marriage bed can ruin you. Paul goes on to say that God bought your body, you are the body of Christ, and for you to share it with a harlot would be the worst kind of insult to the body of Christ. It is a pollution of that which God made holy.
Come back tomorrow when we look at Jesus’ method of curbing temptation.
