So the heart that trusts everything in the Lord is likened here to that tree planted by the waters. It is not fearing the heat, it is not anxious about anything, not anxious about the drought. It remains green, healthy, vibrant, yielding constant, abundant fruit. When we bring our cares, our desires, our anxieties before God in prayer and pray for Him to help us really accept and want His will, not our will regarding that thing, then we are like that tree that is filled with His refreshing regenerative spirit.
