The Bible tells us that faith is the substance of things hoped for and the evidence of things not seen. (Hebrews 11:1) Let me add that faith is the knowledge in your heart that what you believe will come to pass. Faith is not contrary to our circumstances – it is above our circumstances. Faith takes you to a level that is not reached by everyone. Many people choose to live in doubt and worry about what may or may not happen, but people of faith are thoroughly convinced that nothing is impossible with God.
After doing all you can do, stand on the Word of God believing that God will do what He has promised. It takes as much energy to believe as it does to doubt. The question becomes is your energy going to good use as it reaches up toward Heaven believing in God, or is your energy negative and taking you down into the realm of doubt, fear and unbelief?
