Charles Spurgeon Commentary Ephesians 4:3-6

"giving diligence to keep the unity of the Spirit in the bond of peace. [There is] one body, and one Spirit, even as also ye were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all, who is over all, and through all, and in all." — Ephesians 4:3-6 (ASV)

Endeavoring to keep the unity of the Spirit in the bond of peace.

There is one body, and one Spirit, even as you are called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all, who is above all, and through all, and in you all.

Therefore, strive for unity. Woe to those who divide believers – who rob them of love for one another – who set up another gospel which is not another, or in any way detract from the unity of the body of Christ.
