Lust: idolatry of the heart and adultery of the heart
“You have heard that it was said, ‘You shall not commit
adultery’. But I say to you that everyone who looks at a women with lustful
intent has already committed adultery with her in his heart.” – Matthew 5:27-28
I want
to preface this post by saying that the desire for sex is a gift from God. It
is gift to single men to drive them to mature, get a job, grow in Christ and
pursue marriage with a godly woman, in a godly way. It is a gift to married men
to encourage them to pursue intimacy with their wife; by intimacy I do not mean
sex, I do mean an exclusively, close, personal relationship.[1]
The desire for sex is as natural and good as the drive to eat and sleep.
However, unlike other natural desires, the desire for sex is to be filled only
within the bounds of a lifelong, love-filled covenant—dedicated to sacrificially
serving one’s spouse for the glory of God—otherwise known as marriage.
In these
verses and the surrounding passage Jesus takes the liberty as the Word of God to interpret the word of God.[2] Herein Jesus reveals to us that God is not merely
concerned with outward (visible and vocal) conformity to a standard but inwardly
(heart worship) conforming to the ultimate standard: to be perfect as our
heavenly Father is perfect.[3]
To illustrate this Jesus takes a long standing command: not committing
adultery, and reveals its intended purpose: not committing idolatry. Lust is adultery of the heart, because it takes the desire for sex (which is good) and 'aims' or focuses it on a woman to whom the man is not solely dedicated to through covenant. Ultimately
lust is against God, because it exalts its intentions above the command of God
that a man shall leave his father and his mother and hold fast to his wife, and
they shall become one flesh.[4]

Within this exclusively, close, personal relationship spouses are to pursue
each other intellectually, emotionally and physically. This relationship should
be a deepening friendship, with each spouse repenting and forgiving sin, while
honoring and loving the other.
