How many of us are even willing to try? Do we even want to know of our "errors"? The Psalmist apparently thought that everyone has "errors;' and discerning and eliminating them should be a constant effort. An honest effort to identify and remove such is not easy; and is sometimes very unpleasant.
How does one "discern his errors?" Praise God for He has provided the help we need.
In the same Psalm, verses 7-8, we read: "the law of the Lord is perfect, restoring the soul; the testimony- of the Lord is sure, making wise the simple. The precepts of the Lord are right, rejoicing the heart; the commandment of the Lord is pure, enlightening the eyes." That is God's provision for us so we can "discern" our "errors;" and so He will "acquit" us of "hidden faults." His glorious word is indeed a "lamp to my feet, and a light to my path" (Psalm 119:105), if I will but use it for that purpose.
Do we want to discern our errors? We can do so. if we will. --C.A.H.
