Marriage is a covenant
commitment between two individuals making them one. In responding to the
Pharisees’ question on divorce (Matthew 19:1), Jesus turned their attention to
the Creator’s original design, which is that a man should leave his father and
mother and be joined to his wife and, in this joining, the two are made one.
The oneness is a covenant work of God and, thus, what “God has joined
together, let not man separate” (Matthew 19:4–6). Divorce is simply the
outcome of sinful man’s defiance of God, often to justify sexual urges.
Note that the immediate response
to Jesus’ strong statement was a negative reaction, protesting that there must
be legitimate bases for acceptable divorces (Matthew 19:7). Even the disciples
had difficulty with their Lord’s inflexible position (vv. 10–12).
What is really at the heart of
this issue? It is freedom to commit adultery without legal obstruction. This
desired freedom is more deeply rooted in selfish need. Sexual urges are not in
themselves sinful because they were designed by the Creator. However, because
of sin and sin’s corruption of the mind and body, they must be governed by God as
stated in the sixth commandment.
Sin is very deceitful. Often the
urge to sin is very strong, but due to the shame of having to face guilt if
caught violating the law, a way is sought to satisfy that urge without actually
violating the law. Merely looking with lustful intent is one way to avoid shame.
What Jesus wants His followers to understand by His instruction (Matthew
5:27–32) is that covenant oneness is first of all a heart issue. Murder
is the taking of another’s life and is generally motivated by selfish anger in
the heart. Adultery is the taking of another’s covenant oneness
motivated by selfish lust in the adulterer’s heart.
One might argue that having sex
with someone who is not one’s spouse is not a covenant issue. Paul answers that
objection: “Do you not know that he who is joined to a prostitute becomes
one body with her? For, as it is written, ‘The two will become one flesh’”
(1 Corinthians 6:16). One might also argue that it takes two to commit
adultery. Yes, but (and this is politically incorrect) the blame lies with the man.
“Everyone [a nominative masculine singular adjective] who
looks at a woman with lustful intent has already committed adultery with her in
his heart” (Matthew 5:28).
The word translated lustful
intent is often translated “to covet.” It is a compound of the preposition
upon or against and a term signifying a violent movement of air
or fire—a boiling up. Lust is seemingly uncontrollable. Giving into it,
however, is sin. In 1 Corinthians 6:12–20, Paul warns of the sin of sexual
immorality. He argues that the body is meant to honor the Lord, who has raised
us up and made us members of Christ. Then he asks, “Shall I take the members
of Christ and make them the members of a prostitute?” (v. 15). Clearly a
covenantal connection is here, not just with a wife, but also with the Lord,
Himself.
