God the Father is whom Christians worship. God is the Christian's Dad, He is the Creator of all.
The Son, Jesus, died so that we may live. The children love Him and praise Him with great joy, because they are no longer condemn to Hell. Jesus loves us that much!
The Holy spirit was sent by Jesus to comfort the children of God. The children do not worship the Holy spirit, but they are grateful for him.
God is the one and only God; and the Christians worship Him and Him only. God wants us to praise Jesus and follow Jesus, because Jesus is King of kings and Lord of Lords. The children of God listen to what the Father says, because He is the Christian's Dad who loves them very much.
Hope this helps any of the confused Muslims.
