In the Bible (old and new): God is God the Creator. Jesus the Holy Ghost was God in other forms.
"One of the revelations of God given to Moses just before he died was concerning the final Prophet that would come. This amazing Word came to him by the inspiration of the Holy Spirit in Deuteronomy 18:15, “The Lord thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken.” In Deuteronomy 18:18-19 further said, “I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him. And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.” There is no doubt that a Prophet that mentioned here was referring to the final Prophet namely Jesus Christ and not the other of prophets that came after Moses.
In the New Testament Peter made it clear that ‘a Prophet’ mentioned by Moses in Deuteronomy 18:15 was referring to the Lord Jesus Christ. As Peter quoted this verse in his preaching in Acts 3:22-23 saying, “For Moses truly said unto the fathers, A Prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. And it shall come to pass, that every soul, which will not hear that Prophet, shall be destroyed from among the people.” It was “in the name of Jesus Christ of Nazareth” Peter asked the cripple man to “rise up and walk” (Acts 3:6). Though the Old Testament prophets also spoke with authority but Jesus Christ is the final Prophet, the Prophet of all prophets. Thus Deuteronomy 18:15 is the messianic prophecy that is fulfilled in the person of the Lord Jesus Christ."
