If any man's work remains which he built on it, he will receive a reward.

The cup of blessing which we bless, isn't it a sharing of the blood of Christ? The bread which we break, isn't it a sharing of the body of Christ?

"All things are lawful for me," but not all things are profitable. "All things are lawful for me," but not all things build up.

In the same way he also took the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink, in memory of me."

Therefore whoever eats this bread or drinks the Lord's cup in a way unworthy of the Lord will be guilty of the body and the blood of the Lord.

Now I desire to have you all speak with other languages, but rather that you would prophesy. For he is greater who prophesies than he who speaks with other languages, unless he interprets, that the assembly may be built up.

For you most certainly give thanks well, but the other person is not built up.

What is it then, brothers? When you come together, each one of you has a psalm, has a teaching, has a revelation, has another language, has an interpretation. Let all things be done to build each other up.

Now I say this, brothers, that flesh and blood can't inherit the Kingdom of God; neither does corruption inherit incorruption.
