We must obey in faith.
God, who said to Abraham,
"Leave your country, your relatives, and your father's home,
and go to a land that I am going to show you" (Genesis 12:1),
also said to him, "Take your son, your only son, Isaac, whom you love,
and go to the land of Moriah. Offer him there as a burnt offering on
one of the mountains that I will show you" (22:2).
Abraham, who obeyed God's instructions and left Haran
with his wife Sarah and nephew Lot at the age of 75 (12:4-5),
took his beloved son Isaac, whom he had at the age of 100 (21:5), the next morning.
He saddled his donkey, prepared the wood for the offering,
and took two of his servants with him,
setting out for the place God had commanded (22:3).
We also must, like Abraham, obey when God commands us to go
to the place He will show us in faith (Hebrews 11:8).
Furthermore, like Abraham, when we are tested,
we should be willing to offer up our beloved children in faith,
believing that God is able even to raise the dead (Hebrews 11:17, 19).
