2 Chronicles 16:9
For the eyes of the LORD run to and fro throughout the whole earth…
We must discriminate between purity of heart and maturity of Christian character. The entire cleansing received by faith is perfect health of soul; but it is not perfect development. Perfect health is the entire absence of disease. Perfect holiness is the entire absence of sin. Christian purity brings finality to nothing but inbred sin. It is the field cleared of the noxious weeds, not the ripe waving harvest. It is the best preparation for growth, not the consummation of growth. Sin in the heart makes us like a child that is sickly, or a tree with a worm at the root. Some hope by cultivating the graces of the Spirit to grow into purity, which is like a man cultivating the vegetables in his garden to grow the weeds out from about the roots of the plants. Common sense says, "Pluck up the weeds, and give the plant a fair chance for growth and development." This is the Divine method. God cleanses the heart from inbred sin, after which growth is always more rapid and symmetrical; advancement in knowledge, and love of God, and all spiritual excellence, becomes possible then as it never was before. Maturity is the result of experiences, trial, conflict, and requires time; but in purity we grasp by faith the sin consuming power that sweeps the heart clean at a stroke.
