3 John 1:2 (AMPC) says: Beloved, I pray that you may prosper in every way and [that your body] may keep well, even as [I know] your soul keeps well. Our souls (mind, will and emotions) affect our bodies. In order to change our outer circumstances, we must first change what we’re thinking and saying. We must not be moved by emotions. We must say what the word of God says about our bodies, lives & circumstances. We face natural facts everyday; but the spiritual truth trumps these facts all day, every day. We must learn to train our minds to think on what is true, noble, right, pure, lovely, admirable, excellent and praiseworthy (Philippians 4:8). This is the way we transform our lives (Romans 12:2).
