And straightway the father of the child cried out, and said with tears, “Lord, I believe; help Thou mine unbelief.”-Mark 9:24.
When a man first lays hold upon Jesus he is very apt to be in distress if his joy be not always at its full height; he is untrained in spiritual conflict, and easily dismayed; the tremor of his former conviction is upon him, and he is prone to relapse into it. The light which he has received fills him with intense delight, but it is not very clear and abiding; he sees men as trees walking, and is ready to conjure up a thousand fears. The weakness of newborn faith, therefore, calls for the compassion of all who love the souls of men. In addition to their own weakness they are liable to special dangers, for at such times Satan is frequently very active. No king will willingly lose his subjects, and the Prince of Darkness labors to bring back those who have just escaped over the confines of his dominion. If souls are never tried afterwards, they are pretty sure to be assailed on their outset from the City of Destruction to the Celestial City. Bunyan very wisely placed the Slough of Despond at the very commencement of the spiritual journey. The cowardly fiend of hell assails the weak, because he would put an end to them before they get strong enough to do mischief to his kingdom. Like Pharaoh, he would destroy the little ones. He seeks, if possible, to beat out of them every comfortable hope, so that their trembling faith may utterly perish.
Learn from this that a measure of doubt is consistent with saving faith; that weak faith is true faith, and a trembling faith will save the soul. If thou believest, even though thou be compelled to say, “Help Thou mine unbelief,” yet that faith makes thee whole, and thou art justified before God. ~ C.H. Spurgeon
