Foreigners have come into the holy places of the Lord's house.Jeremiah 51:51
In this account the faces of the Lord's people were covered with shame, for it was a terrible thing for men to intrude upon the Holy Place that was reserved exclusively for the priests. Everywhere around us we see similar cause for sorrow. How many ungodly men are now studying with a view to entering the ministry! What a crying sin is that solemn lie by which our whole population is nominally part of a National Church! How fearful it is that ordinances should be pressed upon the unconverted, and that among the more enlightened churches of our land there should be such laxity of discipline. If the thousands who will read this portion will take this matter before the Lord Jesus today, He will interfere and avert the evil that otherwise will come upon His Church. To adulterate the church is to pollute a well, to pour water upon fire, to sow a fertile field with stones. May we all have grace to maintain in our own proper way the purity of the Church as being an assembly of believers and not a nation, an unsaved community of unconverted men.
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 are wearing our wedding garment, lest we ourselves should be regarded as foreigners in the Lord's holy place. 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 a foreigner I must not touch them in case 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 heart! Try me and know my thoughts!"1
