 For correction. That means fixing the things that you've already messed up in your life. God's Word can help you to fix those things. And it is also profitable for instruction in righteousness. It tells us what to do to be right with God. How else are we going to know that? From our own ideas, from our own emotions, we understand what to do to be right with God because God has told us in His Word. And I am grateful to Him.
