For God so loved the world, that He gave His only begotten Son, that whosoever believeth on Him should not perish, but have everlasting life. – John 3:16

Brothers and sisters, since we want to do good, let us preach up our Lord Jesus Christ as the sovereign balm for every sinner’s wound. If you want to be philanthropists, be Christians. If you would bless your fellow-men with the best of all blessings, convey to them the knowledge of Jesus Christ. Do not believe that there is anything you can do for your children which will be more effectual than teaching them about Jesus. Do not think that anything in the workshop can soften the vulgarities, silence the blasphemies, and end the profanities of your fellow-workmen, like setting Jesus Christ before them. When the Moravian missionaries first went to Greenland, they tried to tell the Greenlanders about the existence of a God, and they spent some months in such preliminary subjects before they came to the gospel; but they never gained the attention of the people. Discourses upon such necessary subjects as the Godhead, and the immortality of the soul, and the like, were flavourless to the Greenlanders. It happened one day that one of the missionaries, translating the gospel according to John, read out these words: “God so loved the world, that He gave His Only-begotten Son, that whosoever believeth in Him should not perish, but have everlasting life.” “What is that?” said the Greenlanders. “What is that? We never heard the like of that. Why have you not told us that before?” Nothing had been done till the missionaries came to the gospel itself. Then they reached the Greenlander’s heart-awakened his dormant intellect, and led him to Jesus. Oh, let us keep on with the subject of Christ crucified! …let us look to regeneration by the Son of God, and we shall not look in vain. Nothing has come of newfangled preaching, from the first day till now; but never has the old faith of Jesus failed. Men have been blessed in Jesus, and they shall be blessed in Him as long as the race shall exist. ~ C.H. Spurgeon
