John's Favorite Theme
John's favorite theme was the infinite love of Christ. He believed in God as a child believes in a kind and tender father. He understood the character and work of Jesus; and when he saw his Jewish brethren groping their way without a ray of the Sun of Righteousness to illuminate their path, he longed to present to them Christ, the Light of the world.SL 62.3
The faithful apostle saw that their blindness, their pride, superstition, and ignorance of the Scriptures were riveting upon their souls fetters which would never be broken. The prejudice and hatred against Christ which they obstinately cherished, was bringing ruin upon them as a nation and destroying their hopes of everlasting life. But John continued to present Christ to them as the only way of salvation. The evidence that Jesus of Nazareth was the Messiah was so clear that John declares no man needs to walk in the darkness of error while such light is proffered him.SL 63.1
