Every human activity on earth promotes either God or Satan. Activities create relationships. In the final analysis, relationships operate like marriage.
Marital relationships have time and eternal dimensions. Except Adam, Eve and the Lord Jesus Christ, all of mankind come into the world married to Satan.
The New Birth in actuality means divorce from Satan and remarriage to Jesus Christ. Human marriage is an avoidable option.
Sexual intimacy is a joyful experience. It has a commensurate responsibility. To seek the joy of coition without the responsibility attached to it is the religion of depraved humanity. In this religious atmosphere, Satan is glorified and his kingdom is extolled.
There is a spirit behind every human activity. Sex is not fun. Every act of sexual intimacy outside of wedlock joined by God is a vote for Satan.
