What does Genesis 22:6 mean?
Abraham is resolute. He continues on the path to obey God's command by sacrificing the son he loves as a burnt offering. Leaving the two servants and the donkey behind, Abraham and Isaac walk up toward the mountain together, Isaac carrying the wood for the fire, Abraham carrying the flame and the knife. The fact that Isaac is able to carry the wood strongly suggests he is no child—more than likely, he is a teenager by this time.Again, we're given no hints as to Abraham's emotional state. That does not mean Abraham is unconcerned; Scripture does not record every last detail in every situation. All we know is that Abraham is following a path of obedience, based on his trust in God. This trust is grounded in the many times Abraham has seen God proven righteous, even when the situation seemed impossible.
The following verse will reveal that Isaac still has no idea what Abraham has planned. This, again, suggests a few things about Isaac. An extremely old man would have been unlikely to overpower Isaac, meaning he was also acting in faith, by trusting his father Abraham.
