God’s great master plan
The human body has many parts, but the many parts make up one whole body. So it is with the body of Christ. … All of you together are Christ’s body, and each of you is a part of it. (1 Corinthians 12:12,27 NLT)
Unity within Christ is very important
Now therefore ye are no more strangers and foreigners, but fellow citizens with the saints, and of the household of God. (Ephesians 2:19)
Fellowship together
Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. (Hebrews 10:25 KJV)
