one

This is God's heart - for His people, His body to continue in the unity we were called to.

Eph 4:1-6
1 I, therefore, the prisoner of the Lord, beseech you to walk worthy of the calling with which you were called,
2 with all lowliness and gentleness, with longsuffering, bearing with one another in love,
3 endeavoring to keep the unity of the Spirit in the bond of peace.
4 There is one body and one Spirit, just as you were called in one hope of your calling;
5 one Lord, one faith, one baptism;
6 one God and Father of all, who is above all, and through all, and in you all.
