In seeking for that answer, we must recall the fundamental purpose of the mission of Jesus, and of His loving sacrifice for the salvation of the rest of Father's children. Jesus strove to teach men to know God, and, through His cruel death, to bring men back into the presence of God. All of Jesus's teaching, therefore, was based upon the fact that the chief thing in a man's life is to recognize his divine right as a son of God, and to come into close, real, and constant touch with the Father in heaven. But how shall a man come into such close touch with the Almighty Being who rules the universe? [Sidenote: The necessity of harmony.] {84} Our lives upon the earth are full of illustrations of how necessary it is for us to put ourselves into perfect harmony with our environments when we wish to attain certain ends. If we wish to mingle with so-called society, we must conform to the artificial standards of society in dress, and manners, and speech, and many other things; otherwise, we become outcasts from society and are despised. Or again, if we set up an apparatus for wireless telegraphy, we must, whether we like it or not, make all connections close and in proper way, and we must use the right kind of materials in both the transmitting and the receiving instruments; otherwise, we can neither send nor receive messages. If in the society of men, and in the application of the principles of science, it is so urgently necessary to observe the rules of society and the laws of science, it is very easy to understand that, if we would come into close and constant touch with God, we must observe also the laws of such divine communion. Anything at all that might come between one and real communion with God would be disastrous. Indeed, in the teaching of Jesus, it would constitute the greatest sorrow, the greatest tragedy in human existence. Since it is life eternal to know God, not to know Him, not to find Him, is loss eternal. Although a man may prosper, then, in this life--although he may find his life, as it were, in this world--yet shall he lose it eternally, if he has not found God. If we stop now, and think this out clearly, we may understand very easily what Jesus meant when He said to His disciples, "He {85} that findeth his life, shall lose it; and he that loseth his life for my sake, shall find it."
