Abraham tied Isaac and put him on the altar. He held the knife over Isaac. Abraham was ready to sacrifice his son. But an angel spoke to Abraham. He told Abraham not to sacrifice Isaac. Abraham had obeyed God. God loved Abraham.
What Abraham did was like what Heavenly Father did. Heavenly Father was willing to let his son, Jesus Christ, die for us. Heavenly Father and Abraham loved their sons. Jesus and Isaac loved their fathers and obeyed them.
