In conjunction with Arbor Day — a day dedicated annually to public tree-planting in the U.S. and other countries 
— Ashley Evaro offers a brief theological reflection on the role of trees in the story of our salvation:
Christians should care about National Arbor Day (to those who don’t know, that is today). Even if you are not a devoted celebrator of trees, it is worth your time to stop and consider what wonderful things trees are. Not only are they ascetically appealing, they are present in almost any climate, and provide shade and food. Practicality aside, the Bible illustrates many points through trees. The prevalence of trees and tree imagery in the Bible should shed light on other ways to appreciate and consider these majestic pillars of nature. To explore this idea, let us look at some specific examples of trees in the Bible and examine what they ought to signify to the Believer.
