​The Lord Knows Abraham

Genesis 18:16-19

16  And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way. 
17  And the LORD said, Shall I hide from Abraham that thing which I do; 
18  Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him? 
19  For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.
