Ephesians 1:22-23
And God placed all things under His feet and appointed Him to be head over everything for the church, which is His body, the fullness of Him who fills everything in every way.
Ephesians 2:22
And in Him you too are being built together to become a dwelling in which God lives by His Spirit.
1 Corinthians 12:12-27
The body is a unit, though it is made up of many parts; and though all its parts are many, they form one body. So it is with Christ.
For we were all baptized by one Spirit into one body – whether Jews or Greeks, slave or free – and we were all given the one Spirit to drink.
Now the body is not made up of one part but of many. If the foot should say, “Because I am not a hand, I do not belong to the body,” it would not for that reason cease to be part of the body. And if the ear should say, “Because I am not an eye, I do not belong to the body,” it would not for that reason cease to be part of the body.
If the whole body were an eye, where would the sense of hearing be? If the whole body were an ear, where would the sense of smell be? But in fact God has arranged the parts in the body, every one of them, just as He wanted them to be.
If they were all one part, where would the body be? As it is, there are many parts, but one body.
The eye cannot say to the hand, “I don’t need you!” And the head cannot say to the feet, “I don’t need you!”
On the contrary, those parts of the body that seem to be weaker are indispensable, and the parts that we think are less honourable we treat with special honour. And the parts that are unpresentable are treated with special modesty, while our presentable parts need no special treatment. But God has combined the members of the body and has given greater honour to the parts that lacked it, so that there should be no division in the body, but that its parts should have equal concern for each other.
If one part suffers, every part suffers with it; if one part is honoured, every part rejoices with it.
Now you are the body of Christ, and each one of you is a part of it.
