God knowing you.

We focus much on us knowing God, because He already knows us, right?
The Word testifies that He knows us. He created us.

Psalm 139:15
My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth.

Galatians 1:15
But when it pleased God, who separated me from my mother's womb, and called me by his grace,

Psalm 139:2
Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.

1 Samuel 16:7
But the Lord said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart.

He knows us inside and out, from before we were born, to after our death. God knows his creation. But there are two kinds of God knowing us. The first is that covered above. God knows what He has made. The second is knowing us as His children.

Matthew 7:22-23
 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

Nahum 1:7
The Lord is good, a strong hold in the day of trouble; and he knoweth them that trust in him.

Psalm 1:6
For the Lord knoweth the way of the righteous: but the way of the ungodly shall perish.

John 15:15
Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.

2 Timothy 2:19
Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, let every one that nameth the name of Christ depart from iniquity.

Jeremiah 9:23-25 Thus saith the Lord, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches: But let him that glorieth glory in this, that he understandeth and knoweth me, that I am the Lord which exercise lovingkindness, judgment, and righteousness, in the earth: for in these things I delight, saith the Lord.
