Guard your heart with all vigilance, for from it are the sources of life.
[Prov 4:23 NET]
He who would keep his heart pure and holy, must plant a sentinel at every avenue by which sin may find access there, guarding against none more than the “little” sins, as they are called.
The man of God has his eyes to keep, and so Job said, “I have made a covenant with mine eyes” his tongue, and hence the exhortation, “Keep thy tongue from evil, and thy lips from speaking guile” his ears, and hence the warning, “Cease, my son, to hear the instruction that causeth to err” his feet, and hence David says, “I have refrained my feet from every evil way, that I might keep Thy word.” And since there is no gate of the five senses by which the enemy may not come in like a flood, unless the Spirit lift up a standard against him, we have need to guard every port, and write over every portal, “Here there entereth nothing to hurt or to defile.”
