1 Corinthians 6:15-16
Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a harlot? Certainly not! Or do you not know that he who is joined to a harlot is one body with her? For “the two,” He says, “shall become one flesh.”

Sex is a means of uniting two people into one, in the flesh. It’s not just for pleasure but it’s a synchronization of the two. It’s a kind of baptism that identifies you with the other person, in the same way that the baptism of the spirit identifies you with Christ in the spirit.

Many who are ignorant of this, engage in prostitution, multiple sex partners, sex before marriage, etc. They don’t know that they are mysteriously joining themselves to every other person they have sex with. You become One Flesh with them. Their demons become yours and their problems. Yes, their demons. Sex is one way of demon transference. Many people have contracted certain vices and addictions they can’t explain where it came from (sex is one means).

This shouldn’t be too hard to understand even though it’s a spiritual mystery. If you can contract STIs such as gonorrhoea from someone through sex then this shouldn’t be too far fetched for you.

Do not be ignorant of this spiritual truth.
‘know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?’ (1 Cor 6:19). Receive Strength and Grace to break free from any unhealthy joinings in Jesus Name. Amen.
