Ephesians 4:4-6 explains there is only one God. In fact, the theme of this passage should be "ONE." So that's my title. :)
There is one body; the body of believers saved by the calling of God through the death of Christ. And there is one Spirit; the Spirit of God given to the body as a helper. And there is one hope; the hope we have in Christ. It is the hope of eternal life in the presence of the Almighty God. There is one Lord; Jesus Christ is our Lord. He came and died for the sins of His chosen people, and He was raised from the dead and seated at God's right hand. There is one faith; faith in God is the only saving faith. There is one baptism; the baptism into the family of the one true God is the only sign of true understanding of your need for Christ and your trust in His truth. There is one God and Father of all; there is no other God and no other Father. The one true God created and saved us, and he alone is God. He is the only one over all and through all and in all.
Praise God for He is the One and Only God.
