The tendency among men is, when they grow a little earnest, to expend their zeal upon other people, and frequently in the way of faultfinding. It is wonderfully easy to wax indignant at the indolence, the divisions, the coldness, or the errors of the Christian church, and to fulminate our little bulls against her, declaring her to be weighed in our balances and found wanting, as if it mattered one halfpenny to the church what the verdict of our imperfect scales might be. Why, instead of a tract upon the faults of the church, at the present moment, it would be easy to write a volume; and when it was written it would be wise to put it in the fire.
Friend, mind those beams in your own eye, and leave the Lord Jesus to clear the motes from the eye of his church. Begin at home; there is in-door work to be done. Instead of vainly pointing to the faults of others, pour forth thine earnestness in praising God, and say thou unto thine own heart, “Bless the Lord, O my soul: and all that is within me, bless his holy name."
From a sermon by Charles Haddon Spurgeon entitled "The Saints Blessing The Lord," delivered October 20, 1872.
