godrulz, think this through, please...God's Word is clear!
O Lord, you have searched me and you know me, You know when I sit and when I rise…You discern my going out and my lying down; you are familiar with all my ways (see Psalm 139).
The assertion is that God, knows everything we do. In verse one, David speaks to the Lord and acknowledges that God has looked deep into his heart, and discovered the truth of all that is there. When the Psalmist moves from place to place, and even when he takes his seat or rises from it, God is not caught unaware. He knows everything we do.
godrulz, there is a very good example of this in the New Covenant. Was not the Lord most surely aware of every circumstance in the life of the apostle Paul when he sent an holy angel to tell his apostle that not one person's life on board the ship would be lost? (Acts 27:21-25). How could God have his messenger say such a thing if he did not know all that would take place?
Did he not also know that Paul would do the responsible thing and tell the soldiers that if the sailors did not stay with the ship, they could not be saved? Surely, the Lord knew that the soldiers would make the right decision. The Lord was not waiting to find out what they would do. Though there are passages that indicate that the Lord tests us, and "awaits" our obedience, these are certainly anthropomorphic. There are far too many affirmations in Scripture that God knows all things, from the beginning, to think otherwise.
