'Demonstrate' in the Bible

God publicly displayed him at his death as the mercy seat accessible through faith. This was to demonstrate his righteousness, because God in his forbearance had passed over the sins previously committed.

This was also to demonstrate his righteousness in the present time, so that he would be just and the justifier of the one who lives because of Jesus' faithfulness.

For the scripture says to Pharaoh: "For this very purpose I have raised you up, that I may demonstrate my power in you, and that my name may be proclaimed in all the earth."

But what if God, willing to demonstrate his wrath and to make known his power, has endured with much patience the objects of wrath prepared for destruction?
