The Bible views sex as a normal part of normal human life.
The second chapter of Genesis gives more detail about creation including the creation of woman, and the marriage pronouncement.
“a man will leave his father and his mother and be united to his wife, and they will become one flesh.”
Notice that all this took place before sin came into the world. Sex is not sin, but like every other gift of God, it is made to be used as He directs.
Every nation, city or family has its laws. They are essential for the regulation of society. Sometimes we may feel that God’s laws are there merely to spoil our pleasure, but careful consideration reveals that every one is there for human benefit – individual benefit and the well-being of all society. God reveals Himself as the supreme Father. Every good parent make rules for their children; restrictions that may be resented, but are for the child’s ultimate good. So it is with every commandment of God, including those concerning sex.
Sadly, the first man and woman, Adam and Eve, did not obey the one, simple law that God gave them, with the result that all of us are born dying creatures with a tendency to do wrong. For the meantime, our world is filled with sorrow and evil and death. That is not our present subject although it affects it. Genesis chapter three tells us what happened.
(NOTE: The command our first parents disobeyed did not involve sex. That had already been blessed by God. However it does seem that, against his better judgement, Adam was swayed by his wife. )
Marriage is a divine institution and it should be noticed that its function is not solely for the propagation of the race.
The LORD God said,
“It is not good for the man to be alone. I will make a helper suitable for him.”
(The word here translated “man” applies to either male or female.)
A husband and wife provide for each other what as individuals they cannot provide for themselves. This applies in many aspects of life besides sex. The couple can have greater strength as a couple, than the sum of their individual contributions.
The full benefits of marriage are available only when there is total, life-long commitment the one to the other. God ordains that sexual intercourse should be the crowning expression of intimacy between a man and a woman within marriage.
Problems Within Marriage.
The many and varied problems which can arise within marriage lie outside the scope of this article, but there is one general observation which is worth mention here:
As human beings we all have our weaknesses and our needs. The Bible invites men and women to turn to God
“Cast your burden on the LORD, And He shall sustain you;”
“Come to me, all you who are weary and burdened, and I will give you rest.”
Those who do not have God in their lives, tend to expect of their spouse more support and understanding than any human being can give. Such unreal expectations put stress on the marriage contributing to the shattered relationships and social upheaval which are features of a godless society.
