Our zeal must, however, begin at home. Let us examine ourselves as to our right to eat at the Lord’s table. Let us see to it that we have on our wedding garment, lest we ourselves be intruders in the Lord’s sanctuaries. Many are called, but few are chosen; the way is narrow, and the gate is strait. O for grace to come to Jesus aright, with the faith of God’s elect. He who smote Uzzah for touching the ark is very jealous of his two ordinances; as a true believer I may approach them freely, as an alien I must not touch them lest I die. Heart searching is the duty of all who are baptized or come to the Lord’s table. “Search me, O God, and know my way, try me and know my heart.”
