Ephesians 5:31-32 “For this cause shall a man leave his father and his mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the church.”
The church (the people of God) is referred to in Revelations as the bride of Christ. We also see that Christ will come back to earth to receive his bride. God has established the marriage relationship to reflect his love for us. Christ is pure, and we are sinless in Him and because of Him.
Marriage should be between two pure (not having had sex before) people. The sexual relationship that follows the marriage is something a man and his wife share with only each other. The love and pleasure and procreation God has built into physical union binds a marriage together.
When we go outside God’s bounds for sex, we set up serious problems in our lives. If someone does not control themselves before marriage, what makes them think (or their marriage partner think), they will do so after? Not only do we open ourselves up for natural diseases and for infidelity, but we can set ourselves up for a life time of pain.
In American society today, we see a tremendous increase (over 40 and 50 years ago when purity before marriage was the norm), in unwed mothers, in abortion, in venereal disease and HPV cancer, in rape, in sexual slavery (human trafficking).
Appetites and desires not restrained lead mankind to depravity—think of the Catholic priests’ scandal, the Sandusky scandal, the Clinton scandal, and today’s human trafficking.
