'Sphere' in the Bible

But we will not boast beyond our measure, but within the measure of the sphere which God apportioned to us as a measure, to reach even as far as you.

We are not boasting about work done by others that cannot be evaluated. On the contrary, we cherish the hope that your faith may continue to grow and enlarge our sphere of action among you until it overflows.

so as to preach the gospel even to the regions beyond you, and not to boast in what has been accomplished in the sphere of another.

And He raised us up together with Him [when we believed], and seated us with Him in the heavenly places, [because we are] in Christ Jesus,

So now through the church the multifaceted wisdom of God [in all its countless aspects] might now be made known [revealing the mystery] to the [angelic] rulers and authorities in the heavenly places.

For our struggle is not against flesh and blood [contending only with physical opponents], but against the rulers, against the powers, against the world forces of this [present] darkness, against the spiritual forces of wickedness in the heavenly (supernatural) places.
