The tree, as a symbol rooted by rivers of water, illustrates a believer whose trust in God has matured to the point that fear is entirely absent, even under trial. This is drawn directly from Jeremiah 17:7-8, where the blessed man who trusts in the Lord is compared to a tree planted by the waters, spreading its roots toward that source, and consequently he "will not fear when heat comes." This stands in contrast to the tree of Psalm 1:1-3, which, though planted by rivers of water and prospering, is described only as one whose "leaf shall not wither"—a bend-but-do-not-break posture that still implies the possibility of stress under hardship. The Jeremiah tree represents a further stage of spiritual growth: rather than merely surviving trial without withering, this tree does not even fear the heat when it comes. Its leaf remains green continually, and it is not anxious even in a year of drought. This progression reflects two different levels of spiritual maturity. The tree in Psalm 1 seems to depict a newer or younger person in the Way, one who has made the foundational choice to reject the counsel of the ungodly, the path of the sinner, and the seat of the scornful, and who instead delights in and meditates on the law, or instruction, of the Lord. The tree in Jeremiah, by contrast, portrays someone who has been established in this Way for a longer time, whose root system has spread out extensively toward the rivers of water, and whose trust and hope in the Lord have deepened to the point that fear of trial is no longer present at all. The absence of fear, then, is not the starting point of spiritual life but a fruit of sustained trust and hope built over time through continual reliance on God's instruction. The color green itself reinforces this connection, since it has been shown to reduce stress and anxiety and to foster a sense of peace. The Jeremiah tree's leaves remaining perpetually green corresponds to this reduction of stress and cultivation of peace, suggesting that the lack of fear experienced by the mature believer is tied to a settled, ongoing state of trust rather than a momentary act of endurance. Ultimately, this fearlessness is possible only because the tree is planted next to the rivers of water, and the source of both the instruction and the water is the Lord Himself, as affirmed in John 7:37-38. Trust and hope placed in Him are what allow the mature believer to face drought and heat without anxiety. This points toward the vision in Isaiah 61:2-3, where those comforted by God are called "trees of righteousness, the planting of the Lord," suggesting that the fearless, fruit-bearing maturity depicted in Jeremiah is the ultimate goal God intends for His people, cultivated through sustained trust in Him as the source of both instruction and life.
