The Father is the only true God. You can see throughout the Bible the Father is only one True God, and it is not Jesus Christ. The Bible says that God is the Father of Jesus Christ.
Jesus informed a lot that Father is God, after Jesus and his disciples and the early Christians worshiped God the Father in spirit and truth, what a great offense it is to say that Jesus Christ is God? One of the things that Jesus Christ has often said is that God is the Father of Jesus Christ.
The Father of Jesus Christ is the only true God. Do not give false advice to the contrary, this is done by denying the Father the grace of Jesus Christ. Do not deny that the Father is the only true God.
Jesus Christ is God’s Son and Lord, but the only God is the Father.
We must accept Jesus as “Christ” and “Lord”. Other than that it will go wrong. The only God must be accepted as God.
