We ought to be humbled for our defects, and troubled for every failing in obedience; but we should not be discouraged, though multitudes of weaknesses be upon us, and many infirmities compass us about, in every duty we put our hand to: though we have no righteousness of our own; yet of God, Christ is made unto us righteousness; and that righteousness of his is infinitely better than our own: instead of our own, we have his. O blessed be God for Christ’s perfect righteousness!
