1 Corinthians 11:28-32
11:28 A person should examine himself first, and in this way let him eat the bread and drink of the cup.
11:29 For the one who eats and drinks without careful regard for the body eats and drinks judgment against himself.
11:30 That is why many of you are weak and sick, and quite a few are dead.
11:31 But if we examined ourselves, we would not be judged.
11:32 But when we are judged by the Lord, we are disciplined so that we may not be condemned with the world.
