'Really' in the Bible

Let no one deceive himself. If anyone among you thinks that he is wise in this age, let him become a fool [discarding his worldly pretensions and acknowledging his lack of wisdom], so that he may become [truly] wise.

But I will come to you soon, if the Lord is willing, and I will find out not just the talk of these arrogant people, but [evaluate] their [spiritual] power [whether they live up to their own claims].

I say this to your shame. Can it be that there is not one wise man among you who [is governed by integrity and] will be able and competent to decide [private disputes] between his fellow believers,

Therefore I want you to know that no one speaking by the [power and influence of the] Spirit of God can say, “Jesus be cursed,” and no one can say, “Jesus is [my] Lord,” except by [the power and influence of] the Holy Spirit.

But by the [remarkable] grace of God I am what I am, and His grace toward me was not without effect. In fact, I worked harder than all of the apostles, though it was not I, but the grace of God [His unmerited favor and blessing which was] with me.
