"Anyone who doubts is like a wave on the sea, blown up and down by the wind. That person should not expect to receive anything from the Lord." (James 1:6-7 NCV/NIV)
There are two things that cause self-doubt in your life:
1. Comparing your abilities causes you to doubt your abilities. Instead of looking to God, you start looking around at everybody else. They have more talent, more abilities, more education, or more experience. The moment you start comparing yourself to other people, you're going to be filled with self-doubt.
The Bible says that it's dumb to compare yourself to other people (2 Corinthians 10:12). God doesn't want you comparing yourself to anybody else. He wants you to be unique. He wants you to be you.
2. Remembering your past failures causes you to doubt your abilities. Remembering your past failures is kind of like putting a movie in your mind of all your mistakes and playing it over and over. It tortures you to death, and you hate doing it.
God does not want you focusing on your past. If you stay focused on your past mistakes, you can't get on with your present, and God can't use you in the future. God says to forget the past.
Don't let your past doubts or guilt keep you from being used by God. God says, "I don't care what your past is. I want to use you!"
Talk About It
How many times a day do you compare what you own, have or have not accomplished, or look like to another person?
What do you want God to accomplish with that wasted time instead?
