In Genesis 22, God tests Abraham's faith and asks him to offer his one and only son, who he loves so much and waited 25 years for, as a sacrifice. Abraham knows God's voice, His promises over his life, and that he can trust Him faithfully. Abraham obeys. Just like Jesus carrying His wooden cross on his shoulders, Isaac carries the wood for his sacrifice on his. Just like Jesus rescues us from eternal death, He rescues Isaac. The mountain God directed Abraham to go is believed to be the same area that Jesus died on the cross for us. God sent a ram to replace Isaac in death just like Jesus replaces us. God sent a ram for them for now, but the Lamb was still to come.
