" He is like a tree planted by streams of water,
which yields its fruit in season
and whose leaf does not wither.
Whatever he does prospers" (Psalm 1:3).
I was meditating on this passage yesterday and started using my imagination. As I thought about how trees are planted and grow, I realized they don't do anything to make it happen. They don't plant themselves, someone else does. They don't concentrate really hard to grow better, to be more fruitful. They just have to be trees. We cannot of our own strength be better, more spiritual Christians. We cannot cause our lives to be fruitful.
For the Christian, this analogy brings us to John chapter 15 of Jesus being the vine and our need to abide in him. "I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing" (verse 3).
Let us trust in God's grace to enable us to grow in him as we abide, then we too can be fruitful trees.
