“Teach the children to see Christ in nature. Take them out into the open air, under the noble trees, into the garden; and in all the wonderful works of creation teach them to see an expression of His love. Teach them that He made the laws which govern all living things, that He has made laws for us, and that these laws are for our happiness and joy. Do not weary them with long prayers and tedious exhortations, but through nature’s object lessons teach them obedience to the law of God.“

The Desire of Ages, 516, 517.
