When the Lord registers the nations, he will say, “They have all become citizens of Jerusalem.” – Psalms 87:6 NLT
The Psalmist’s voice was in contrast to the majority opinion of his time. When most of his fellow countrymen believed their relationship with God was exclusive to Jews, he spoke of a day when people from all nations would call Jerusalem their home–a day when all nations recognize Yahweh as their God.
The Jews had learned that they were God’s chosen people. They were chosen for two reasons: to be the people through which the Messiah would come, and to introduce the world to God. They were special, but their selection gave them a sense of pride. Instead of sharing God with the world, they thought themselves superior. Instead of introducing the world to God, they shut the world out from Him.
The Bible clearly demonstrates that all who come to God through Christ are chosen by Him. That makes us special, too. But our knowledge of being special creates the danger that we will also feel superior.
Like the nation Israel (and even to a deeper degree), we have been given the task to introduce the world to God through the Messiah, Jesus. As we do, we must never pre-qualify who can and who cannot receive the gospel. Only God gets to do that.
