Doubt is natural within faith. It comes because of our human weakness and frailty… Unbelief is the decision to live your life as if there is no God. It is a deliberate decision to reject Jesus Christ and all that he stands for. But doubt is something quite different. Doubt arises within the context the faith. It is a wistful longing to be sure of the things in which we trust. But it is not and need not be a problem.
