Of course, God is the One who founded the nation of Israel through Abraham. Primarily, however, this refers to God [Himself] indwelling the Holy of Holies in the Tabernacle and, later on, in the Temple. Any unbeliever (somebody who rejected God and denied God was with the Jews) who stepped into the Holy of Holies would have been atomized, because he had no relationship with the living God. And wherever the Ark of the Covenant went, the Israelites won. There was no question that God was with the nation of Israel.

God is still wherever the Holy of Holies was, but He is there in the sense that God is omnipresent (He is present everywhere). However, God's presence did leave the Holy of Holies in the sense that His powerful, particular manifestation left. In a vision, Ezekiel saw God's Shekinah Glory leave the Holy of Holies/Temple and, therefore, the nation of Israel. However, we are going to see that He left the nation of Israel in stages. Ultimately, according to the pattern given, that leads to destruction.

That is exactly what happened; the Holy of Holies/Temple was totally destroyed. It was destroyed to the point that, just one generation after 70 A.D., nobody knew where the Holy of Holies had been located [specifically]. People would come into Jerusalem and ask, but nobody knew more than a very general area.

God created man with no evil in his nature, and God was with Adam and Eve in the Garden where He walked and talked with them.

Does that not see strange to say? God had intended that everybody was to be born indwelt with Holy Spirit (filled with God). But once they rejected Him, God left the human race in the sense that nobody was to be born filled with Holy Spirit anymore. At this stage, God's Holy Spirit works on every human being, but it is from the outside of the human race.

This will occur in the millenium and in all eternity.

Children can respond to spiritual food, have access to God, and are heard by God when they pray because God is in children. At the beginning, children do not have a spirit, though there is a place within each individual for a spirit (just like there is a place for the Temple's Holy of Holies).

Clearly, this is not the same as an adult believer whose spirit is indwelt with Holy Spirit. Instead, children are at the age of innocence, so God indwells their souls (their fundamental level of consciousness). Practically speaking that means yes, they can pray to God and they can even communicate with Him. You can tell children that Messiah Jesus is in them and He will help them, because Messiah does indwell every child's soul, as does Holy Spirit.

That is the way every child begins; he is created in the image of God, and God's presence is with him. The child has already sinned, but he is just not fully aware of what it means to sin. And God does not count sin unless there is the knowledge of the sin. In God's mind, the child is not righteous, but he is innocent.

At a certain age [determined by God], every human being will understand right from wrong because it is inherent (inborn knowledge). No matter what culture an individual (including a Gentile, moralist, Jew, or religious person) is brought up in, he has an original knowledge of God which he rejects and distorts at that age (which I believe is around 18 or 20 years old or maybe even older). And there is not one human being that has ever accepted God at that point.

The Ezekiel picture of God rebuilding the Temple (one of the jewels of the Old Testament) is a picture of an individual's spirit that has been regenerated.
