God forbid that I sin, but if I do, it is not I. It is my flesh working out the Adam nature that is in me. God forbid that I do sin and then reap the trials and testings and consequences of experiential sin, possibly bringing reproach to the precious Master.
People often go on with the same struggles. They are good people, and they love God. But they can't grasp this message spiritually, though they know it intellectually. They cannot experience it because they don't start at the right place. We need to fix our eyes on Jesus, the crucified and glorified Lamb. This is the Christian life.
Always start with the fact that you are in Christ. Never use that fact to continue in sin, but use it to be like Him, to be conformed to His image, to be renewed in His mind (Ephesians 4:23), and to be transformed by His Word.
As we avail ourselves to the teaching of God's Word, categories of doctrine are woven together to become a strong wall. We are protected by a "wall of fire." Through doctrine, God's glory reflects His nature within. That wall of fire is a Finished Work provision that can never change.
