Read Ezekiel chapter 37.

Jesus said: He who is not with Me is against Me; and he who does not gather with Me scatters. Luke 11:23

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 He says, “The two shall become ONE FLESH.” But he who is joined to the Lord is ONE SPIRIT with Him. 1 Corinthians 6:15-17
