Well, lets try this again. Maybe I was just having a senior moment
I wonder if the faith shown here is special. What we see in Abraham is an almost child like faith. He believed God and then acted upon it. He did not no where he was going or how he was going to have an heir with Sarah but he believed God and it was counted to him for righteousness according to Hebrews 11.
Christ told us that we needed to come to him as a child. Perhaps this is what He meant.
James said that if we can see a thing then it is not faith, God is pleased when we take His word for something and then ACT ON IT. This is the kind of faith I think Abraham was showing.
Again James said faith without works is dead. Abraham showed his faith by the works that he did. God said it so he did it.
One scripture that was an eye opener to me whas when God told Abraham that NOW HE KNEW that Abraham would fear and obey Him. It was like He didn't know until Abraham was willing to "ACT" on what God said about sacrificing Isaac.
Gen 22:12 And He said, Do not lay your hand on the lad, nor do anything to him. For now I know that you fear God, since you have not withheld your son, your only one, from Me. Raymond
