Stop Looking In The Rear View Mirror
Have you ever noticed? When you look in the rear view mirror too long you will start driving out of the lane go off the path, sometimes even cause an accident.
Looking in your past can also cause this affect. If we constantly look in our past it can cause us to go off the path of righteousness. We could end up making bad decisions. We could waste time bothering ourselves with dumb questions. "Why did I do that?" or "If only I could go back and change the past." Yes, we should learn from our past. But, Unfortunately here is nothing we can do to change it. Not one thing can change our past. So why keep thinking, If I only did this or that differently. This is wasted energy. Energy that could be used in a more positive manner such as praying.
If God forgives our sins then why do we always re-hash. He throws them into the sea of forgetfulness and remembers them no more. So why should we?
He will turn again, he will have compassion upon us; he will subdue our iniquities; and thou wilt cast all their sins into the depths of the sea. Micah 7:19
We should think on good things.
Philippians 4:8 Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
Sometimes when we are in some sort of depressed or negative state this is hard to do. I suggest that you write down all the things you are thankful for and all the blessings that God has blessed you with. Keep the note with you. When feeling down just take it out and read it. Perhaps you will want to add more stuff to it.
