Praise the LORD from the earth...you mountains and all hills, fruit trees and all cedars ... (Psalm 148:7-9)
Interesting article about rethinking the purpose and use of trees. Interesting also to think about whether using trees in particular ways as suggested is for "man to give them purpose" or whether it's for man to "recognize a purpose and usefulness they meet and are already fit for".
Indeed ALL things, the sun, the moon, the stars of the sky, the trees, the organs of the body, etc., ALL have purpose though for a time man may not recognize or understand or appreciate it... but that doesn't mean with wisdom, greater investigation, and insight it cannot be discovered. Indeed, as the Psalmist writes:
Let them praise the name of the LORD, for his name alone is exalted; his splendor is above the earth and the heavens.
