'Shown' in the Bible

Where is the wise man (philosopher)? Where is the scribe (scholar)? Where is the debater (logician, orator) of this age? Has God not exposed the foolishness of this world’s wisdom?

each one’s work will be clearly shown [for what it is]; for the day [of judgment] will disclose it, because it is to be revealed with fire, and the fire will test the quality and character and worth of each person’s work.

With regard to the question about people who have never married, I have no command from the Lord, but I give my opinion as one shown mercy by the Lord to be trustworthy.

But by God's grace I am what I am, and his grace shown to me was not wasted. Instead, I worked harder than all the others not I, of course, but God's grace that was with me.
