1 Corinthians 6:16

¹⁴ By His power God raised the Lord from the dead, and He will raise us also.

¹⁵ Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and unite them with a prostitute? Never!

Or don’t you know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.”

¹⁷ But he who unites himself with the Lord is one with Him in spirit.

¹⁸ Flee from sexual immorality. Every other sin a man can commit is outside his body, but he who sins sexually sins against his own body.

Do read the surrounding verses too, because the context often says more than a single verse.
