'Demonstrates' in the Bible

Even when the fool walks along the road, his sense is lacking and he demonstrates to everyone that he is a fool.

But if our unrighteousness demonstrates the righteousness of God, what shall we say? The God who inflicts wrath is not unrighteous, is He? (I am speaking in human terms.)

But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.
