This is a truism, that, we live by faith and not by sight. I've often heard it said by many: "I'll believe it when I see it". But, how many things we believe to be true or exist although we cannot see them? For example, air -- we cannot see air, but we know that it exists. In fact we can't live without it. We do not see knowledge, but we certainly believe that many possess it. We do not see other planets besides the earth and we believe that there are other planets. The person who believes even when a thing is not visible in the moment displays the courage that is not with one who must see to believe. How much do you believe?
