Abraham put his only son Isaac on the altar and lifted his knife to kill him..
Why would he do this?
Who in their right mind would kill their son?
A man with a lot of faith.
But what was his faith in?
Did he believe God would provide an offering like a lamb or a ram?
That God would give him another son to carry on his lineage like he promised?
What was Abraham's faith really in?
The answer is found in Hebrews Chapter 11.
