The way to prevent much sin is to deal with it in its first motions in the heart. An oak tree when just a plant, is much easier to uproot, a little spark is easier quenched than a blazing fire. When you complain of the power of your corruptions, are you perhaps to blame because you have long suffered the habit of the sin to grow unchecked and so strong. If you had crushed the very first motions, inclinations you would not be perhaps struggling to break the power of strong lusts now. It is foolishness to put this work off. If you can’t stamp on the first thoughts of sin, how on earth will you do it when they have taken root, gotten established in your heart? This is the way to keep the conscience clean and pure. A tender conscience has a deep impression of the sinfulness of sins allowed to grow, “O wretched man that I am” (Romans 7:24). And you cannot maintain peace and assurance of your freedom from condemnation, nor continue your glorying in and enjoyment of God, but by dealing with them. O how small a matter will break a tender Christian’s peace! A wrong look or word will do it, you must not allow even half a thought escape without challenge, take it and quench it immediately in the blood of Golgotha.
