How vivid on both its sides is the picture, and how truthfully it represents the case! The faculties of the human heart and mind are limited, like the productive powers of the ground. Neither the understanding nor the affections are endowed with an indefinite capacity of reception. The soil, even where it is rich and deep, may be soon exhausted, especially where the more gross and greedy weeds have taken up their abode. You are convinced of sin and begin to cry for pardon; you plead the Redeemer's sacrifice and righteousness; you grieve over your own backsliding, and come anew to the blood of sprinkling; the twin emotions, confession and prayer, struggle together in your breast, "Lord, I believe; help thou mine unbelief." Thus far, it is well. The field has been broken; the seed has been covered in the ground; the covered seed has sprung; the sprung seed has grown apace and now seems near maturity. The evil spirit that seeks to spoil this fair promise seldom comes in the form of speculative unbelief. When you begin to fall away, you do not begin by abjuring your religion, or denying the Lord. You do not pull the grown but unripe corn up by the roots and cast it over the hedge: the harvest is marred in a more secret and silent way. The kingdom of the wicked one, cunningly in this matter imitating the kingdom of God, "cometh not with observation." Weeds spring up among the wheat. At first they are small and scarcely perceptible; the inexperienced, apprehending no danger, are put off their guard. The first leaves which these bitter roots put forth are generally smooth, tender, and apparently harmless, giving to the inexperienced eye no indication of their rough and ravenous nature. But these thorns, if they are not watched, curbed, and killed, may yet cause the loss of the soul.
