6 Then the lord said to Cain, "Why are you angry? Why is your face downcast?7 If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it."

How do you react when someone suggests you have done something wrong? Do you move to correct the mistake or deny that you need to correct it? After Cain's gift was rejected, God have him the chance to right his wrong and try again. But Cain refused. The next time someone suggests you are wrong, take an honest look at yourself and choose God's way instead of Cain's.
