Faith is not necessary when you know how things are going to work out, - that's knowledge. It's in the time of unknowing that having faith is what sees you through to the other side. Faith is what gives you strength. Faith is that light in your heart that keeps on shining even when it's all darkness outside. Now is the time to keep that faith alive!
I live so much of my life on faith. I realize that believing is essential. I heard a song this evening that basically said if God never does anything else for me He's already done enough. Wow! My faith has insured so much. He has done enough for me, but I have faith that he has made a lot of decisions for my future!
