3. For by the grace (unmerited favor of God) given to me I warn everyone among you not to estimate and think of himself more highly than he ought [not to have an exaggerated opinion of his own importance], but to rate his ability with sober judgment, each according to the degree of faith apportioned by God to him.
4. For as in one physical body we have many parts (organs, members) and all of these parts do not have the same function or use,

6. Having gifts (faculties, talents, qualities) that differ according to the grace given us, let us use them: [He whose gift is] prophecy, [let him prophesy] according to the proportion of his faith;
7. [He whose gift is] practical service, let him give himself to serving; he who teaches, to his teaching;
