Now to show or illustrate how faith works instantaneously always, let us suppose you are a parent and one of your children is lost. It is your youngest child but one. You have hunted until you are exhausted, and find no trace of the child. Your heart is sick; a load as heavy as lead bears down upon you. You can think of a dozen different things that could have happened to the child; he may have been kidnapped, may have been run over and killed, may have fallen into the water and drowned, may be weeping his heart out somewhere. At last the whole neighborhood gets out to search, and you, exhausted, sit impatiently waiting. By and by you hear some one halloo. Then you hear another. And then some one runs up excitedly and says, "The child is found, safe." The very moment you believe that news the load lifts, the heart is light, the soul is happy. Tears of joy flow freely. But suppose it proves a premature report, and by and by another comes and says it is a mistake, that the child was found dead. Then all your joy is turned immediately to sadness. Faith always works instantaneously. The quickness with which faith works has been illustrated by this: Suppose some one rushes into an office of philosophical, higher-critical professors, and cries, "Fire!" You would see those hard-boiled skeptics, if they believed the cry, rush unceremoniously and indecorously out of that building with all speed. People may scoff at faith working with lightning speed; but every exhibition of it only proves that it does. Now you mentioned that at times you feel as though you believe strongly, and at other times you feel as though your faith is leaving you. You are making a great mistake mixing up your faith with your feelings. They never did mix; and all who try to mix them only get into trouble; for faith is one thing and feelings are another. The only way for you to know that you have faith is to believe something. Do you believe anything? If so, then you have faith. Do you believe in God? Then you have faith in God. Faith is believing, just as seeing is seeing and hearing is hearing. If you see something, you know you have sight; if you hear something, you know you have your hearing; and if you believe, you have faith. Faith in God is just like faith in anything else. God has said He will do or has done something for you. Do you believe He has done something for you? Do you believe He has done or will do that thing? If so, that is faith.
