1 Corinthians 12:24 (ESV)

24 which our more presentable parts do not require. But God has so composed the body, giving greater honor to the part that lacked it,

When one body part falls into dishonour, the whole body is shamed. Thus it is in the interest of the whole body that certain body parts should receive extra care. The same holds true in the church. God has wisely composed the church in such a way that all members will ultimately be honoured.

Paul does not stop to explain what this looks like in practice. We can assume that it is connected to the way in which the Spirit has chosen to distribute gifts, or to the way in which different gifts are treated in the church.
