This devotional is about Isaiah 45.
The early part of this chapter prophesied that Cyrus, king of Persia, would return God’s people to their Promised Land (vv. 1-13). This would happen despite Cyrus’s unbelief in God (v. 4e); he would serve as God’s chosen agent anyway (v. 13). This prophecy was fulfilled in Ezra 1 around 539 B.C.
The rest of this chapter, starting around verse 14, looks further into the future. It envisions a day when nations all over the world will come to Israel seeking the true God (vv. 14-17). Although the nations say that God “has been hiding himself” (v. 15a) in Israel, God himself says, “I have not spoken in secret, from somewhere in a land of darkness” (v. 19). Instead, he has been revealing himself to humanity from the beginning of time as the one and only God, the only true person deserving of worship (v. 20). The Lord welcomes worshippers from every nation on earth. “Turn to me and be saved,” he said, “all you ends of the earth” (v. 22). Just as he created the earth to be inhabited (v. 18) he wants his kingdom to be inhabited with people from all over the world–and it will be, someday.
But when is this great day when people from different languages, cultures, and locations come streaming to Israel seeking God? Verse 23d-c says, “Before me every knee will bow; by me every tongue will swear….” Paul alluded this verse in Philippians 2:10-11 when he wrote, “…at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue acknowledge that Jesus Christ is Lord, to the glory of God the Father.” So this prophecy awaits us in the future still when Christ reigns on earth in his kingdom. Until then, we have been given the opportunity and responsibility of going to every nation to tell them that Jesus saves. As we deliver the gospel–ourselves and through missionaries around the world–God is appointing people to eternal life and marking them as his for that day when we will reign with him in his kingdom.
Do you see how important the task of world evangelism is? It is important because every person who comes to Christ has been saved for eternity from God’s wrath. But it is also important in the fulfillment of God’s word which prophesied that God would save people from all over the world, that they would come seeking to know him and become worshippers of his for eternity. This is why we send missionaries. This is why we preach the gospel. This is why we witness personally to others about Jesus. When the world comes to bow before Christ and confess that he Lord, all will be right in creation again, finally. And all of this is, as Paul wrote in Philippians 2:11, “to the glory of God the Father.”
