Today, when people say they cannot believe, it is not a mental problem; it is a matter of the will of the heart- they do not want to believe. Some say they have certain 'mental reservations,' mental hurdles which they cannot get over. My friend, your mind is not big enough to take even one little hurdle. The problem is never in the mind but in the will. There is sin in the life, and a man does not want to turn to God; he does not want to believe Him.
