The fashionable religion of the time has so molded character that youth who make a profession of Christ scarcely mention His name to their associates. They converse of many subjects, but the precious plan of redemption is not made a theme of conversation. Suppose that as practical Christians we should change this order of things, and “show forth the praises of Him who hath called us out of darkness into His marvelous light.” If Christ is abiding in the heart by faith, you cannot keep silent. If you have found Jesus, you will be a true missionary. You are to be enthusiastic in this matter, and let those know who do not appreciate Jesus that you have found Him precious to your soul, that He has put a new song in your mouth, even praise to God. MYP 200.2
My young friends, will you begin your Christian life as those whose hearts are warmed with the love of Jesus? You will never know how much good you may do by speaking tenderly sensible, serious words regarding their souls’ salvation to those who do not claim to be children of God. On the other hand you may never know until the judgment how many opportunities to be Christ's witnesses you have left unimproved. You may never know in this world the mischief you have done to some soul by your little acts of frivolity, your cheap talk, your levity, which was wholly inconsistent with your holy faith. MYP 201.1
