1 Corinthians 11:27-32

27So then whoever eats the bread or drinks the cup of the Lord in a way that is unworthy [of Him] will be guilty of [profaning and sinning against] the body and blood of the Lord.

28But a person must [prayerfully] examine himself [and his relationship to Christ], and only when he has done so should he eat of the bread and drink of the cup.

29For anyone who eats and drinks [without solemn reverence and heartfelt gratitude for the sacrifice of Christ], eats and drinks a judgment on himself if he does not recognize the body [of Christ].

30That [careless and unworthy participation] is the reason why many among you are weak and sick, and a number sleep [in death].

31But if we evaluated and judged ourselves honestly [recognizing our shortcomings and correcting our behavior], we would not be judged.

32But when we [fall short and] are judged by the Lord, we are disciplined [by undergoing His correction] so that we will not be condemned [to eternal punishment] along with the world.
