Preaching the Gospel, Preparing a People
The Bible is very clear that there is only One God, not 2, 3 or 4 or any other number.
Jesus is God Who became a human and also came to this earth, so is the Holy Spirit and the Father, plus the Angel of the Lord. Very simply they are all the same Person. God alone has the ability to be in different places at the same time in His total Person, not as fragments of Himself, he also has different identities but all the same person.
