'Dealing' in the Bible

But as for me Paul, I entreat you by the gentleness and self-forgetfulness of Christ--I who when among you have not an imposing personal presence, but when absent am fearlessly outspoken in dealing with you.

And judging by the stupendous grandeur of the revelations--therefore lest I should be over-elated there has been sent to me, like the agony of impalement, Satan's angel dealing blow after blow, lest I should be over-elated.

since you want proof that the Messiah is speaking through me. He is not weak in dealing with you but is making his power felt among you.

For even though He was crucified in weakness [yielding Himself], yet He lives [resurrected] by the power of God [His Father]. For we too are weak in Him [as He was humanly weak], yet we are alive and well [in fellowship] with Him because of the power of God directed toward you.
