What went through his mind?

Today I listened to the story of Abraham and Issac. I understand that Abraham was listening to God and followed the instructions given to him.  I really kind of wonder what was Issac thinking? He is being obedient to not only God but also his earthly father. He was willing to lay his life on the alter so that the will of God would be fulfilled. I am amazed at his willingness to surrender all of who he is to see his earthly father obey God. As a child of an earthly father I wonder if I would allow myself to lay down my physical life so that he would be able to obey a request of the Lord.  I see a parallel of God doing the very thing with Jesus Christ. God sacrificing His son so that relationship could be restored with His creation. I know it's not exactly the same thing but God being obedient to Himself so that restoration would be accomplished though His son Jesus.
I know from an early age I was taught by my parents the importance of being obedient. Sometimes I understood why I needed to listen and do as instructed, but there has been those other times that just didn't make sense until after the fact. As a parent I see the the lessons being revealed to me. I see the point of following through.  I am thankful that God has afforded me the opportunity to see Himself revealed and listen and do as He would have me to do. I'm thankful to Abraham's story and to his son who was so willing to obey.
