Omnipotent (All powerful) is the only Omni in scriptures. We have to view God as HE says he operates, not what they teach in churches. Omniscient means to know all things, it does not denote fortune telling. Calvinist do not believe in a fortune telling God, but a God that by design causes things, not just crystal ball gazing. So a big chunk of the church world would not agree. In fact it's in their statement, God does not deal with man through foreknowledge, but that can't be 100% correct as God knows the heart of man, and has a very solid idea of what that man is going to do next. Hearts can change though.
God also has to try a man to know what His heart will do.
2Ch_32:31 Howbeit in the business of the ambassadors of the princes of Babylon, who sent unto him to enquire of the wonder that was done in the land, God left him, to try him, that he might know all that was in his heart.
God gives according to the heart, not according to election or foreknowledge.
Jer_17:10 I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.
So, just two scriptures have to be perfect in line with God knows the number of hairs on our head, knows when a bird falls from the sky, and some scriptures we have to ask if God just had blotted groups of people out of his mind, until He was called to go check it out.
It's not as simple as God is omniscient, but where we go, the Holy Spirit Goes, and God is there as the Holy Spirit connects us to the Father.
Eph 2:18 For through him we both have access by one Spirit unto the Father.
So before we cry Heresy, Brother Mike always has lots of scriptures to examine, and scriptures all must match, and must change our thinking on things thought previously, least we not grow and be stuck in what someone else believes that is wrong. Not a position we need to be in. We never ignore 5 scriptures and hold onto 2, that is called religion. Every single scripture must be taken into account of those scriptures made known to us.
Blessings.
