He sees us through many troubles and He heals our bodies many times. The Bible tells us that faith is being sure of what we hope for and certain of what we do not see. And it tells us that without faith it is impossible to please God, because anyone who comes to Him must believe that He exists and that He rewards those who earnestly seek Him. He promises that if you have faith as small as a mustard seed you can say to this mountain, 'Move from here to there' and it will move and that nothing will be impossible for you. Faith is not something that we can be taught, or just say we believe.
Faith is something that grows.
It helps if a child has grown up in a home that demonstrates faith, but this same child must experience it for himself. First of all, faith is believing that God is real. Faith is trusting God completely with all things, knowing that He alone can be trusted. He can be trusted with all aspects of our lives. As we grow in experience with our Lord we do learn to have that total trust, that no matter how the situation looks that our God is both interested and caring.
