And another thing, dear heart, in that Genesis account. Abraham said to the servant that they would go up to the mountain and “they could come down again”. Abraham believed in Isaac’s resurrection if he was, indeed, slain. Because all of God’s promises were through Isaac’s seed. Therefore, Abraham, knew that God was true to His word —so, he would have to resurrect Isaac in order for fulfill His promises.....that little bit of text is often overlooked....
Yes, you are correct. And we understand it the more when we read the following in Hebrews Chap 11...
“Heb 11:17-19 When God tested Abraham, faith led him to offer his son Isaac. Abraham, the one who received the promises from God, was willing to offer his only son as a sacrifice. (18) God had said to him, “Through Isaac your descendants will carry on your name.” (19) Abraham believed that God could bring Isaac back from the dead. Abraham did receive Isaac back from the dead in a figurative sense.”
