Sexuality is distinctively a gift from God. It is intended to be one of God’s greatest blessings.
Because of its immense potential, it has equal ability to enrich or blight your life. For this reason, much is said in the early portion of Proverbs about wise sexual conduct (cf. 2:10-20; 5:1-23; 6:20-35; 7:1-27).
One can only imagine the earnest passion with which Solomon wrote: “My son, attend unto my wisdom, and bow thine ear to my understanding: that thou mayest regard discretion, and that thy lips may keep knowledge. For the lips of a strange woman drop as honeycomb, and her mouth is smoother than oil: but her end is bitter as wormwood, sharp as a two-edged sword. Her feet go down to death; her steps take hold on hell” (Proverbs 5:1-5).
As every loving father desire, Solomon wanted his offspring to have the most joyous, abundantly blessed life possible. For this to be experienced, his son needed to keep his marriage bed undefiled (cf. Hebrews 13:4). The strange (i.e. illicit, immoral, sinful) behaviors of fornication prior to marriage and adultery while married had to be avoided.
The greatest blessings of human sexuality only come to those who are virgins at their wedding and live monogamously ever after.
