It’s a crying shame that many members of a congregation have become lazy and negligent in enjoying the Lord’s Supper, or that the congregation also perhaps tolerates such tranquility of those in their midst who goes on for a year or longer without coming to the Lord’s table. The Lord’s Supper is a means of grace as much as God’s Word, through which the Lord distributes His sure mercies to His Christians. This sacrament makes the forgiveness of sins especially, personally certain to individuals. It thus strengthens the faith of Christians in a particular way, sustains and strengthens their spiritual life and promotes the growth of the inner man. A Christian who diligently uses this sacrament in true faith will grow and increase in the knowledge of God’s will and evermore be complete in sanctification. A congregation in which a more faithful, more diligent use of this means of grace is in full swing, will therefore also internally grow and thrive and rightly build on their most holy faith. And on the other hand, if a congregation is poorly prepared in the proper and diligent use of this sacrament, then they thus deprive themselves of a great blessing that God has chosen for them. The inner growth of the congregation will no longer joyfully progress, but begins to stand still and regress, even if perhaps the congregation is still externally growing and increasing.
