Romans 12:3-5

Amplified Bible

³ For by the grace [of God] given to me I say to everyone of you not to think more highly of himself [and of his importance and ability] than he ought to think; but to think so as to have sound judgment, as God has apportioned to each a degree of faith [and a purpose designed for service]. ⁴ For just as in one [physical] body we have many parts, and these parts do not all have the same function or special use, ⁵ so we, who are many, are [nevertheless just] one body in Christ, and individually [we are] parts one of another [mutually dependent on each other].
