Genesis 22:9

Then they came to the place of which God had told him. And Abraham built an altar there and placed the wood in order; and he bound Isaac his son and laid him on the altar, upon the wood. (Genesis 22:9 NKJV)

Abraham was 100 years old when Isaac was born. Now, Isaac was old enough to carry enough wood for a sacrifice. If he was 12, then Abraham was 112 when he bound Isaac. Isaac could have fought or run away from an old man, but maybe he didn't. Maybe he was silent, trusting his father. Like Jesus didn't fight back when He went to the cross. When Our Father sacrifices His Son. Have you thanked Him for that lately?
