We are to “look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal; but the things which are not seen are eternal.”[413] The exchange we make in the denial of selfish desires and inclinations is an exchange of the worthless and transitory for the precious and enduring. This is not sacrifice, but infinite gain. [Sidenote: _Love That Constrains_] “Something better” is the watchword of education, the law of all true living. Whatever Christ asks us to renounce, He offers in its stead something better. Often the youth cherish objects, pursuits, and pleasures that may not appear to be evil, but that fall short of the highest good. They divert the life from its noblest aim. Arbitrary measures or direct denunciation may not avail in leading these youth to relinquish that which they hold dear. Let them be directed to something better than display, ambition, or self-indulgence. Bring them in contact with truer beauty, with loftier principles, and with nobler lives. Lead them to behold the One “altogether lovely.” When once the gaze is fixed upon Him, the life finds its center. The enthusiasm, the generous devotion, the passionate ardor of the youth find here their true object. Duty becomes a delight, and sacrifice a pleasure. To honor Christ, to become like Him, to work for Him, is the life’s highest ambition and its greatest joy. “The love of Christ constraineth.”[414] _THE HIGHER COURSE_ _“Since the beginning of the world men have not perceived by the ear, neither hath the eye seen, what He hath prepared for him that waiteth for Him”_ _The School of the Hereafter_ “THEY SHALL SEE HIS FACE; AND HIS NAME SHALL BE IN THEIR FOREHEADS” [Sidenote: _Its Location_] Heaven is a school; its field of study, the universe; its teacher, the Infinite One. A branch of this school was established in Eden; and, the plan of redemption accomplished, education will again be taken up in the Eden school. “Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love Him.”[415] Only through His word can a knowledge of these things be gained; and even this affords but a partial revelation. The prophet of Patmos thus describes the location of the school of the hereafter:— [Sidenote: “_A New Earth_”] “I saw a new heaven and a new earth; for the first heaven and the first earth were passed away.... And I John saw the holy city, New Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.”[416] “The city had no need of the sun, neither of the moon, to shine in it; for the glory of God did lighten it, and the Lamb is the light thereof.”[417] [Sidenote: _Conditions_]
