The path of the righteous is level; you, the Upright One, make the way of the righteous smooth." NIV
"The way of the just is uprightness: thou, most upright, dost weigh the path of the just." KJV
Since we live in a cursed world, all humans walk out their lives on paths that are filled with debris and potholes. However, those who are righteous in the eyes of the Lord, who is the only upright one, will smooth out those rough spots and work out the problems so that passage onward will be less of a burden and more of a blessing.
Heavenly Father, we're sorry that we forget that life in this world is difficult and You have told we will have problems here. When we come across stumbling blocks and things that stop our walk, help us to remember that You are with us to make those rough places smooth. You will work out all those tribulations for us, Your righteous ones. In Jesus' name, Amen.
