Nothing, in fact, has done more harm to Christianity than the practice of filling the ranks of Christ's army with every volunteer who is willing to make a little profession, and talk fluently of his experience. It has been painfully forgotten that numbers alone do not make strength, and that there may be a great quantity of mere outward religion, while there is very little real grace. Let us all remember this. Let us keep back nothing from young professors and inquirers after Christ. Let us not enlist them on false pretenses. Let us tell them plainly that there is a crown of glory at the end. But let us tell them no less plainly, that there is a daily cross in the way.
