Just because one's comely parts have 'no need' does not mean those, whose service seems less comely, do not have purpose, too. In fact, when one's gift shines above another, that was God's doing, not ours; Psalm 100:3.
Those members of the body, which seem to be more feeble, are NECESSARY ... not only for reasons yet to be understood, but because, also, God hath tempered the body!
When Jesus warned that forbidding others 'trying to grow in service for Him' would cause suffering (Matthew 19:14), fruit inspections were not a given option. In fact, all one has to do, to verify if Christ is the head of any church, is to check out the church's list of Prayer Requests. And (no matter how long that list), few, but the physical needs, are even listed.
When one member suffers, the oven temperature goes up wherein 'all members' are made to suffer; because the degree of being tempered has to make up for another's lack in being able to fulfill what God has called them to do.
If you are not experiencing suffering, too, you may not be part of the body of Christ at all. For we which live are alway delivered unto death for Jesus' sake, that the life also of Jesus might be made manifest in our mortal flesh. 2 Corinthians 4:11 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together. Romans 8:17
Is not this the fast that I have chosen?
to loose the bands of wickedness, to undo the heavy burdens,
and to let the oppressed go free, and that ye break every yoke?
Isaiah 58:6
If Christ be not risen in our heart, then is our preaching vain, and your faith is also vain. 1 Corinthians 15:14
God tempered the body so there would be no schism, but that members would finally realize 'having the same care, one for another,' is not negotiable. We are to have the same care for the custodian as the preacher, the same respect for the follower as the leader, the same love for the sinner as our most cherished friend; wherein all who have a heart to serve God are welcomed.
Therefore, those members of the body whose service we think to be less honourable ~ upon these we bestow more abundant honour. And, once we do so, we will begin to discover one should not have thought more highly of themselves than they ought (Romans 12:3); for it is God who builds His church. But also, ministries will begin to flourish wherein all members will rejoice!
If my people, which are called by my name,
shall humble themselves, and pray, and seek
my face, and turn from their wicked ways;
then will I hear from heaven, and will forgive
their sin, and will heal their land.
2 Chronicles 7:14
