David was one of God's prophets. In Psalm 89 David is telling us about the coming Messiah.
Lets cut to the bottom line. Were the prophets looking for the appearance of a triune God or a man who God would exalt above all other men and anoint Him as King?
Psalms 89:26-27
26 "He will cry to Me, 'Thou art my Father,
My God, and the rock of my salvation.' 27 "I also shall make him My first-born,
The highest of the kings of the earth. NAS
Does God have a God? If you have answered this question I missed it, but what do we read in Scripture? Here is just one of many Scriptures that call the Trinity into question:
Ephesians 1:3-4
3 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, 4 just as He chose us in Him before the foundation of the world, that we should be holy and blameless before Him. NAS
If Jesus is God then someone forgot to tell Paul and they also forgot to tell Jesus.
John 20:17
17 Jesus said to her, "Stop clinging to Me, for I have not yet ascended to the Father; but go to My brethren, and say to them, 'I ascend to My Father and your Father, and My God and your God.'" NAS
Revelation 3:12-13
12'He who overcomes, I will make him a pillar in the temple of My God , and he will not go out from it anymore; and I will write upon him the name of My God , and the name of the city of My God , the new Jerusalem, which comes down out of heaven from My God , and My new name. 13'He who has an ear, let him hear what the Spirit says to the churches.'
NAS
