You will never get better. You will never get a job. You will always be alone. You will never make it. You will never prosper.
Fear is something that has hindered people as much as anything else.
But, for the child of God, it is not natural that we live in fear and defeat. Jesus came and died that we might have life and have it more abundantly. If you do go through a time when you are afraid, my advice is that you talk to the Lord about it. Tell him exactly how you feel and allow Him to help you. He is always there and He will never let you down.
