A Testing of Faith
Place a small trash can with a clean liner in a corner of the room. Tell your children to get a favorite toy, movie or video game, then ask them to place it in the trash can. If they protest, ask them whether they trust you and know that you love them.
Explain that God never intended for Abraham to sacrifice his son Isaac. (You can return your kids' toys as you say this.) God was testing Abraham's faith. He was also giving Abraham a glimpse of His plan to save humanity: God's only Son would be offered as the sacrifice for our sins. He would have thorns on His head, similar to the ram caught by his horns in the thicket.
Genesis 22: 1-13
