Philippians 2:12b “work out your own salvation with fear and trembling.”
Not to work it into our lives, Ephesians 2:9, but to work it out by our lives, by our obedience, by our daily behavior, or to show what is on the inside. The Christian life is a working concern. We should have an eagerness to show it off like a child would do with a new toy. In other words displaying fruit, Galatians 5:22,23. Just like one would a gold mine operating, exploiting, and getting top value for what is securely your possession.
