Do not be angry with yourselves

"And now, do not be distressed and do not be angry with yourselves for selling me here, because it was to save lives that God sent me ahead of you."

Genesis 45:5

If you've ever done evil to another and you still get sick to your stomach with guilt over the thought of it, do not worry.  For, although you meant to harm that person at that time, God had a plan all along.  He knew what was going to happen before it happened, and he knew what you were going to do before you did it; God, had the blessing awaiting the outcome of the whole situation, a blessing that you may never know, but a tremendous blessing all the same.  

Therefore, now is the time to forgive yourself, repent, stand up tall, focus on Christ, and move forward with your life.  It's all going to be OK, God knows your heart and for the guilt and repentance you feel - he will bless you for it.  Remember, everything works out for good to those who rely on Christ :-).
