To me this verse goes with verse 2. We may think we know what’s right but in the end we can be sure that God’s plan for us is good. We can let go of our desires and truly seek what it is He wants for us and know that His way is the best way. The use of rivers (channels) remains me how there could be many paths before us but only one will lead to life. Knowing the Lord turns it wherever He wills is knowing that you’ll always end up on the right path if you listen to Him.
