You serve a God of miracles. A miracle is the supernatural intervention of the God of Heaven into the problems of your life.
By believing in the power of the God of the Bible, you have nothing to lose and everything to gain. At some point in your life, you will either be forced to live in the potential of your faith, or with the consequences of your doubt.
“Jesus said unto him, If thou canst believe, all things are possible to him that believeth.”
