I will display my glory among the nations; and all the nations shall see my judgment that I have executed, and my hand that I have laid on them. The house of Israel shall know that I am the LORD their God, from that day forward. And the nations shall know that the house of Israel went into captivity for their iniquity, because they dealt treacherously with me. So I hid my face from them and gave them into the hand of their adversaries, and they all fell by the sword. I dealt with them according to their uncleanness and their transgressions, and hid my face from them. Therefore thus says the Lord GOD: Now I will restore the fortunes of Jacob, and have mercy on the whole house of Israel; and I will be jealous for my holy name. They shall forget their shame, and all the treachery they have practiced against me, when they live securely in their land with no one to make them afraid, when I have brought them back from the peoples and gathered them from their enemies’ lands, and through them have displayed my holiness in the sight of many nations. Then they shall know that I am the LORD their God because I sent them into exile among the nations, and then gathered them into their own land. I will leave none of them behind; and I will never again hide my face from them, when I pour out my spirit upon the house of Israel, says the Lord GOD. (Ezekiel 29:21-29, NRSV)
God will show all nations who he is.
He will make himself known to all nations.
And as he does this his Spirit will be poured out upon the house of Israel, and through that, all will see His glory.
So allow him to use you to make himself known to all the nations around you.
