While on this earth, Jesus presented timeless truths using varied illustrations. In this way, He appealed to different classes of humanity. Let us follow His example, especially drawing lessons from the things of nature. Reference: E.G. White, "The Upward Look," p. 167.

And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin. Matthew 6:28.

The church of Christ is dependent on Him for her very existence. Only through Him can it gain continued life and strength. The members are to live constantly in the most intimate vital relationship with the Saviour. They are to follow in His steps of self-denial and sacrifice. They are to go forth into the highways and byways of life to win souls for Him, using every possible means to make the truth appear in its true character before the world.

The truth is to be presented in various ways. Some in the higher walks of life will grasp it as it is presented in figures and parables. As men labor to unfold the truth with clearness, that conviction may come to their hearers, the Lord is present as He promised to be...

In His wonderful Sermon on the Mount, Christ used the lilies of the field in their natural loveliness to illustrate a great truth. His language is adapted to the opening intellect of child life. The great Teacher brought His hearers in contact with nature, that they might listen to the voice which speaks in all created things; and as their hearts became tender and their minds receptive, He helped them to interpret the spiritual teaching of the scenes upon which their eyes rested. The parables, by means of which He loved to teach lessons of truth, show how open His spirit was to the influences of nature, and how He delighted to gather spiritual teaching from the surroundings of daily life.

The birds of the air, the lilies of the field, the sower and the seed, the shepherd and the sheep—with these Christ illustrated immortal truth. He drew illustrations from the facts of life, facts of experience familiar to the hearers—the hid treasure, the pearl, the fishing net, the lost coin, the prodigal son, the houses on the rock and on the sand. In His lessons there was something to interest every mind, to appeal to every heart. Thus the daily task, instead of being a mere round of toil, bereft of higher thoughts, was brightened and uplifted by constant reminders of the spiritual and the unseen.

The Lord Jesus would have the true philosophy of nature’s great lesson book opened before the mind... We need workers who will gain breadth of mind by studying the book God has opened before us of His created works. Angels cooperate with those who proclaim the truths represented by the things of nature. These things are not God, but they are specimens of God’s handiwork.—Letter 223, June 2, 1905, to J. A. Burden.
