That's why God asked Abraham to sacrifice his only child?
At first, Abraham’s “child”, was not a “baby”, but a responsible young man who knew what it means to sacrifice to God.
God challenged Abraham to see who is on first place of his life, God or Isaac...
God decided not to let the Abraham to kill Isaac, and already prepared a ram to be sacrificed instead of that boy. (see Genesis, chapter 22)
