1 Corinthians 12 :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.  24 For our comely parts have no need: but God hath tempered the body together, having given more abundant honour to that partwhich lacked: 25 That there should be no schism in the body; but that the members should have the same care one for another.

We have to realize that even what we might think is the most insignificant part of the body is important because the body cannot function properly without it.  Again it shows us that even the jobs that are not out front are just as important as the one that are in full view. Rich and poor, old and young, white and black, all make up the family of God. Even sometimes there are parts of the body that are not that presentable but God had a purpose for them, just like he has a purpose for everyone that makes up a body of Christ. The thing that bonds us together is the Lord and we are all family.
