God's plan to save us from sin has always been the cross of Jesus Christ, where we can be forgiven for anything we have done. Can you find the shadow of the cross?
Now Cain said to his brother Abel, “Let’s go out to the field.” And while they were in the field, Cain attacked his brother Abel and killed him. — Genesis 4:8 (NIV)
After Adam and Eve were banished from the Garden of Eden because of what had seemed a small sin, all generations to come would be under the curse of sin. Cain and Abel, the first sons of Adam and Eve, were born with the same choice to obey or disobey God as their parents. Sadly, they made wrong choices, too. God knew their hearts, just like He knows ours, and after Cain murdered his brother, God drove him from His presence. We are all children of Adam. We all have the same sinful nature, and we are all driven from the presence of God. But He has a plan, and if we turn to Jesus Christ we will be forgiven.
