…we pray you in Christ’s stead, be ye reconciled to God. – 2 Corinthians 5:20
“Be you reconciled to God” is a text for saints as well as for sinners! Children may quarrel with a father as well as rebels with a king. There must be oneness of heart with God, or there is an end to communion and, therefore, must the conscience be purged…Beloved, if our consciences were more fully developed than they are, we should have as great a sense of the frequency of our uncleanness as ever the thoughtful Israelite had of his danger of ceremonial uncleanness. I tell you solemnly that the talk which we have heard lately about perfection in the flesh comes of ignorance of the Law and of self. When I have read expressions which seem to claim that the utterers were free from sin in thought, word and deed, I have been sorry for the deluded victims of self-conceit and shuddered at their spirit. The sooner this boasting is purged out of the Church of God the better. God’s true people have the Spirit of Truth within them, convincing them of sin and not the proud and lying spirit which leads men to say they have no sin!
True saints abide in the place of penitence and constant faith in the atoning blood and dare not exalt themselves as the Pharisee who cried, “God, I thank You that I am not as other men are.” “There is not a just man upon earth that does good and sins not” Why, beloved, according to my own experience, we are constantly being defiled by being in this polluted world and going up and down in it. As a man could not take a walk without stumbling over a grave, nor could he shut himself up in his house without the danger of death entering there, so are we, everywhere, liable to sin. It seems all but inevitable so long as we are in this body and in this sinful world that we should come into contact with sin in some form or other—and any contact with sin is defiling. ~ C.H. Spurgeon
