Is it possible to always be rational, to never lapse into irrational thinking, to never commit any fallacy? It is possible even though it seems impossible. It seems impossible since each of us has two minds. These two minds are in a battle to the death. As Christians, we each have a natural, carnal mind, and we also have the mind of Christ. But we can’t reconcile these two minds. So we’re limited this way. And yet the Holy Spirit will lead us to the vision He provides. And He Who started a good work in us will continue to complete it. ^{(Philippians 1:6)} He’ll complete it in everyone who’s willing. So He continues the work. He continues until we come to the unity of the faith and knowledge of the Son of God. All must come to unity as one complete man. We must continue to the measure of the stature of the fullness of Christ. ^{(Ephesians 4:11-13)}
