Faith is truly the evidence of what we hope for. If we keep the faith, we are promised that it shall be rewarded. Close your eyes and think of all of the many things in your lifetime that you have given up on. I don't have enough time to review all of my contributions to the black hole, but I know they are plentiful.
Confidence is belief.
It is the truest form of Faith. God gives us promises and visions and He who begins a good work in you is faithful to perform it. God is not some sadistic tease that dangles dreams, like carrots, in front of us to drive us crazy. God will reward our faith in Him. I must admit that I have to constantly remind myself of that.
