Genesis 22:9

Then Noah built an altar to Yahweh and took of every clean animal and of every clean bird and offered burnt offerings on the altar.

Then Yahweh appeared to Abram and said, “To your seed I will give this land.” So he built an altar there to Yahweh who had appeared to him.

Then he arranged the wood and cut the ox in pieces and placed it on the wood.

By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was offering up his only son,

Was not Abraham our father justified by works when he offered up Isaac his son on the altar?
