Fear of the LORD is the foundation of true wisdom. All who obey his commandments will grow in wisdom. Praise him forever! (Psalm 111:10 NLT)
If You want to "grow in wisdom" just start obeying what God says! There are at least two reasons why this works: 1. You have to read God's word in order to obey it and the result is that you grow wise through an ever increasing knowledge of the Truth. 2. You gain wisdom through your life experiences that comes while obeying the Truth. Wise people recognize that God sees things from a different perspective and know that what He commands us to do is always right.
