Isaac was Abraham’s son of promise…a dearly loved son in his old age, but more importantly, the future promise of the Jewish Nation. But here, God is asking Abraham to surrender this precious promise, not out of temptation, for God cannot be tempted, nor tempt anyone to do evil (James 1:12-13) but in order to refine Abraham’s character. God was asking Abraham to totally give up this promise…to relinquish all rights to it…and to remain loyal and obedient to God, not the promise. Maybe the Lord has asked you to do the same thing…surrender a promise He’s given you to see where your loyalties lie…in that promise or in Him.
