'Really' in the Bible

There is not one who is really wise, nor one who is a diligent seeker after God.

You, however, are not devoted to earthly, but to spiritual things, if the Spirit of God is really dwelling in you; whereas if any man has not the Spirit of Christ, such a one does not belong to Him.

Why, this is really the reason you pay taxes; for tax-gatherers are ministers of God, devoting their energies to this very work.

And it is really this which has again and again prevented my coming to you.
