Genesis 4:1-16

"You will be accepted if you do what is right. But if you refuse to do what is right, then watch out! Sin is crouching at the door, eager to control you. But you must subdue it and be its master." v.7
How do I react when someone suggest i have done something wrong? Do I move to correct the mistake, or deny that I need to correct it?

After Cain's gift was rejected, God gave him the chance to right his wrong and try again. God even encouraged him to do this! But Cain refused, and the rest of his life is a startling example of what happens to those who refuse to admit their mistakes. The next time someone suggest you are wrong, take an honest look at yourself and choose God's way instead of your own way like Cain.
