God's pinpoint accuracy
When God asked Adam the question, "Where art thou (Gen 3:9)?", it was not because Adam was so good at hide and seek that he could even beat God. It was a rhetorical question designed to get Adam to see where sin had taken him spiritually, and to lead him to repentance. God knew exactly where Adam was, and He knows exactly where we are spiritually, emotionally, physically, and financially. The purpose of prayer is not to inform God of our status and needs (Mt 6:32-33). It is to connect us with Him and His will relationally (1Jn 5:14-15).
God is everywhere, or omnipresent (Ps 139). He cannot literally go somewhere or not be somewhere. However, He does concentrate His presence at certain times and places. When God manifested Himself on Mt. Sinai to Moses, He was also down below with the children of Israel. When God manifested Himself in the flesh as Jesus Christ, He was still omnipresent (Jn 3:13). If you have even been in a gathering of people where the presence of God was manifested, you may have marvelled as I have at the pinpoint accuracy of God. It is amazing how physically close people can be and yet one can be completely overwhelmed by the Holy Ghost and the person right next to them can be totally oblivious to God. Why and how is that?
In Job 1-2, Satan came among the angels before God, but God knew exactly who he was. The devil could no hide himself among the angels. In Ezekiel 9, the angels were instructed to go through the city and mark all those who were seeking God, and to destroy all those who were not. In Matthew 7, Matthew 13, and Matthew 25, God makes it clear that He can distinguish among individuals who is really His and who is not, even when those who are not are right among and pretending to be the children of God.
In Exodus 14, the Israelites were by the Red Sea and the Egyptians came out to recapture them. The pillar of cloud and fire that had been guiding Israel now became a barrier between them and the Egyptians. After Israel passed through the Red Sea, the Egyptians attempted to follow them. God looked at the Egyptians through the cloud and caused the Red Sea to destroy them. Apparently the Egyptians thought the cloud would disguise them so God could not tell they were really the enemy. Some people think just because they are among the people the cloud and fire of the presence of God is manifest for, they too will be counted among the faithful. God looks right through the cloud and sees us for who we really are. He can separate people that distinctly and precisely. God knows our hearts and our behavior, and He knows whether or not we are truly seeking Him or not. He can precisely pinpoint his manifestation so that two people standing right next to each other can have completely different experiences - one totally connected and the other playing on their cell phone. God can also do this positively by ministering to many people about different things on different levels all at once. At the end of the world, God will separate the sheep from the goats (Mt 25). He knows us, He loves us, and He can pinpoint where we are.
