'Operation' in the Bible

And there are [distinctive] ways of working [to accomplish things], but it is the same God who produces all things in all believers [inspiring, energizing, and empowering them].

For if the operation of the law, giving death, recorded in letters on stone, came with glory, so that the eyes of the children of Israel had to be turned away from the face of Moses because of its glory, a glory which was only for a time:

Will not the operation of the Spirit have a much greater glory?

For if the operation of the law, producing punishment, had its glory, how much greater will be the operation of the Spirit causing righteousness?

For through the Law I died to the Law and its demands on me [because salvation is provided through the death and resurrection of Christ], so that I might [from now on] live to God.

Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.
