You want to discover God's will. God's will shall reveal to you what is good, what is well pleasing to God, and what is perfect. I find it fascinating that Paul did not say to defeat evil with knowledge, or defeat evil with logic, or defeat evil with irrefutable arguments, or defeat evil by exposing evil for what it is. Unquestionably, knowledge is important, but evil can confuse knowledge. Certainly, there is a place and need for logic, but evil can pervert logic.
Sound arguments have their role and place, but evil loves to exploit irrefutable arguments.
Surely evil needs to be exposed for what it is, but evil is very skilled at making itself look so good and making what is right look so vile. The instruction to Christians in the epistles to do good continues on and on. He created us in Christ Jesus, and He designed us to do good works. All Scripture is inspired by God and is profitable for teaching, for reproof, for correction, for training in righteousness, that the man of God may be adequate, equipped for every good work. It reveals what is wrong in me and my life.
