We are all built for relationship - for community.
This is part of the Imago Dei - the image of God that exists in every one of us. God is a perfect trinity of Father, Son, and Holy Spirit. The Godhead exists in perfect unity and community. He designed us to be in relationship with one another.
As believers, we have been radically changed at the very center of our being and God, in His ultimate, eternal, perfect wisdom has placed us in community with one another.
As we “do life together” - we’ll grow in the depth of our relationships with one another. Primarily because of what is plainly spelled out in Ephesians 4:1-6 – I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called, 2 with all humility and gentleness, with patience, bearing with one another in love, 3 eager to maintain the unity of the Spirit in the bond of peace. 4 There is one body and one Spirit—just as you were called to the one hope that belongs to your call— 5 one Lord, one faith, one baptism, 6 one God and Father of all, who is over all and through all and in all.
