1 Corinthians 6:16; 1 Corinthians 7:29; 1 Corinthians 10:15; 1 Corinthians 10:19; 1 Corinthians 15:50

16 Or do you not know that the one who joins himself to a prostitute is one body with her? For He says, "THE TWO SHALL BECOME ONE FLESH."
29 But this I say, brethren, the time has been shortened, so that from now on those who have wives should be as though they had none;
15 I speak as to wise men; you judge what I say.
19 What do I mean then? That a thing sacrificed to idols is anything, or that an idol is anything?
50 Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable.
