To him who learns thus to interpret its teachings, all nature becomes illuminated; the world is a lesson-book, life a school. The unity of man with nature and with God, the universal dominion of law, the results of transgression, can not fail of impressing the mind and moulding the character. [Sidenote: _The Child’s Teacher_] [Sidenote: _Opportunity for Nature Study_] These are lessons that our children need to learn. To the little child, not yet capable of learning from the printed page or of being introduced to the routine of the schoolroom, nature presents an unfailing source of instruction and delight. The heart not yet hardened by contact with evil is quick to recognize the Presence that pervades all created things. The ear as yet undulled by the world’s clamor is attentive to the Voice that speaks through nature’s utterances. And for those of older years, needing continually its silent reminders of the spiritual and eternal, nature’s teaching will be no less a source of pleasure and of instruction. As the dwellers in Eden learned from nature’s pages, as Moses discerned God’s handwriting on the Arabian plains and mountains, and the Child Jesus on the hillsides of Nazareth, so the children of to-day may learn of Him. The unseen is illustrated by the seen. On everything upon the earth, from the loftiest tree of the forest to the lichen that clings to the rock, from the boundless ocean to the tiniest shell on the shore, they may behold the image and superscription of God. So far as possible, let the child from his earliest years be placed where this wonderful lesson-book shall be open before him. Let him behold the glorious scenes painted by the great Master Artist upon the shifting canvas of the heavens, let him become acquainted with the wonders of earth and sea, let him watch the unfolding mysteries of the changing seasons, and, in all His works, learn of the Creator. [Sidenote: _Antagonistic Forces_] In no other way can the foundation of a true education be so firmly and surely laid. Yet even the child, as he comes in contact with nature, will see cause for perplexity. He can not but recognize the working of antagonistic forces. It is here that nature needs an interpreter. Looking upon the evil manifest even in the natural world, all have the same sorrowful lesson to learn,—“An enemy hath done this.”[120] [Sidenote: _The Interpreter of Nature_] Only in the light that shines from Calvary can nature’s teaching be read aright. Through the story of Bethlehem and the cross let it be shown how good is to conquer evil, and how every blessing that comes to us is a gift of redemption.
