Adam and Eve's first two kids didn't get along very well. Cain loved to work in the garden. He did a great job raising tasty vegetables and fruits. Abel preferred hunting. He skillfully hunted for tasty meat and skins for clothing. Both boys worked very hard to do well at their job.
Adam and Eve started the first homeschool. They taught their sons all the great things they learned about God's creation and what God expected of them.
Before Adam taught the lesson about offering sacrifices for their sins, he probably told his boys about that terrible day when he and Eve disobeyed God by eating fruit from the Tree of Knowledge of Good and Evil.
One day Abel and Cain offered a sacrifice to God for their sins. They each brought their best, Abel brought an animal, Cain brought his best from his garden.
But God said Cain's sacrifice couldn't be used. He gave Cain a chance to bring a different sacrifice, the kind Adam taught him to bring.
Instead of fixing the problem, Cain became jealous, and killed his brother.
God gives us chances to do our best for Him. What can you try to do better this summer?
