1 Corinthians 12

After having taught the Corinthians that the Gifts of the Spirit are given to every member -

"...dividing to every man severally as he will." (New Testament | 1 Corinthians 12:11)

...he teaches that each member is essential in the Lord's Church comparing each saint to the member of the body -

"For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ." (New Testament | 1 Corinthians 12:12)

"For the body is not one member, but many.
15 If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?
16 And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body?
17 If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling?
18 But now hath God set the members every one of them in the body, as it hath pleased him." (New Testament | 1 Corinthians 12:14 - 18)

His logic continues -

"...the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
22 Nay, much more those members of the body, which seem to be more feeble, are necessary:
23 And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness." (New Testament | 1 Corinthians 12:21 - 23)

When we are missing a body part, it is highly noticable for -

"...having given more abundant honour to that part which lacked..." (New Testament | 1 Corinthians 12:24)

But to each of the members, whether considered weak or strong, comely or not -

"...covet earnestly the best gifts..." (New Testament | 1 Corinthians 12:31)

Or in other words, covet gifts of the Spirit over wordly gifts, and strive to develop those gifts within you.
