Charles H. Spurgeon

The evil heart which still remaineth in the Christian, doth always, when it is not attacking or obstructing, still reign and dwell within him. My heart is just as bad when no evil emanates from it, as when it is all over vileness in its external developments. A volcano is ever a volcano; even when it sleeps, trust it not. A lion is a lion, even though he play like a kid; and a serpent, is a serpent, even though you may stroke it while for a season it slumbers; there is still a venom in its sting when its azure scales invite the eye. My heart, even though for an hour, it may not have had an evil thought, is still evil. If it were possible that I could live for days without a single temptation from my own heart to sin, it would be still just as evil as it was before; and it is always either displaying its vileness, or else preparing for another display. It is either loading its cannon to shoot against us, or else it is positively at warfare with us. You may rest assured that the heart is never other than it originally was; the evil nature is still evil; and when there is no blaze, it is heaping up the wood, wherewith it is to blaze another day. It is gathering up from my joys, from my devotions, from my holiness, and from all I do, some materials to attack me at some future period. The evil nature is only evil, and that continually, without the slightest mitigation or element of good. The new nature must always wrestle and fight with it; and when the two natures are not wrestling and fighting, there is no truce between them. When they are not in conflict, still they are foes. We must not trust our heart at any time; even when it speaks most fair, we must call it liar; and when it pretends to the most good, still we must remember its nature, for it is evil, and that continually.
