Charles Spurgeon Commentary Romans 12:4-5

"For even as we have many members in one body, and all the members have not the same office: so we, who are many, are one body in Christ, and severally members one of another." — Romans 12:4-5 (ASV)

This is why there is diversity. If the hand were made exactly like the foot, it would not be one-tenth as useful; and if the eye only had the same ability as the ear, it would not be able to see, and the whole body would be a loser as a result. Do we begin to compare eyes, and ears, and feet, and hands, and say, "This is the better ability"? No.

They are each one necessary. So do not compare yourselves with one another, for if you are in the body of Christ, you are each one necessary. The distinctive trait that you possess, and the distinctive trait that your brother possesses, both have their place in the collective body and must be precious in God's sight.
