'Demonstrates' in the Bible

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 for us, in that while we were still sinners, Christ died for us.

The fact that you have lawsuits among yourselves demonstrates that you have already been defeated. Why not rather be wronged? Why not rather be cheated?
