Iron sharpens iron. Great post. Perhaps this should be the prayer of our hearts in this matter:Who can discern his errors? Acquit me of hidden faults. Also keep back Thy servant from presumptuous sins; let them not rule over me; then I shall be blameless, and I shall be aquitted of great transgression. Let the words of my mouth and the meditation of my heart be acceptable in Thy sight, O Lord, my rock and my Redeemer. Psalm 19:12-14
