On Catechizing our Children -C.H. Spurgeon-

Unless we are careful over the young, there may be none to bear the Lord’s banner when we sleep among the clods. In matters of doctrine, you will find orthodox congregations frequently change to heterodoxy in the course of thirty or forty years, and that is because too often there has been no catechizing of the children in the essential doctrines of the Gospel.

—Charles Spurgeon
