The Bible tells us that “faith is the substance of things hoped for, the evidence of things not seen.” Throughout the ages there have been people whose faith has proved that there is a spiritual power which we can use.
It was his complete belief in this power, his absolute reliance on it, and his conscious use of it for every purpose that made Jesus the outstanding spiritual teacher of all the ages. When we read the words of Jesus we realize that he had complete reliance on this spiritual power; that he based everything he did on his understanding of it, his acceptance of it, and his use of it.
For instance, he would say to someone who was sick, “Do you believe that I can heal you?” And then, when the man said, “Yes,” he would say, “Your faith hath made you whole.” And he told his followers that if they had faith the size of a grain of mustard seed – which is one of the smallest of all seeds – they could remove mountains of obstruction.
When the Bible said that faith is the substance of things hoped for and the evidence of things not seen, it was plainly stating that our faith does actually lay hold of a spiritual power which is real substance. It is not an illusory or a visionary something, but an actual substance in the universe, a paver which really exists and which we can consciously use.
