There is only one true God and your Judge's God is not a Trinity. What did you suppose you could ever say to your Judge to justify serving your three person God, a God which is not his God? For serving any God but our Lord's God is idolatry, a grievous sin. Just as your Triune God is totally absent from Scripture without a single mention, the Triune God will be a no-show on Judgment Day. Your three person idol fabricated by men will be AWOL and won't be there to help you on the Day of Wrath and the righteous judgment of God who will render to every man according to his works on the Day when the Father, the Living God, will judge all men through a man whom He has appointed. The only true God is the Lord's God and there is no God but His God. You won't be judged by any Triune God and no Triune God will be anywhere to be found on that Day or anytime after. The only true God will judge the world through a man whose God is that only true God. No Triune God will be found anywhere in the new creation of God.
But each in his own order: Christ the first fruits, after that those who are Christ’s at his coming, 24 then comes the end, when he hands over the kingdom to the God and Father, when he has destroyed all rule and all authority and power. 25 For he must reign until he has put all his enemies under his feet. The last enemy that will be destroyed is death. For He has put all things in subjection under his feet. But when it says, “All things are put in subjection,” it is evident that He is excepted who put all things in subjection to him. 28 When all things are subjected to him, then the son himself also will be subjected to Him who subjected all things to him, so that God may be all in all. 1 Corinthians 15:23-28
