Every nation has a unique purpose in God’s plan. Israel’s purpose is to reflect God’s character, host His presence and facilitate His worship.
Note God’s declaration of Who He is before He states His choice of and purpose for Israel. God challenges anyone who would dare disagree.
Isaiah 44:6 – 8: “Thus says the Lord, the King of Israel, and his Redeemer, the Lord of hosts: ‘ I am the First and I am the Last; besides Me there is no God.
And who can proclaim as I do? Then let him declare it and set it in order for Me, since I appointed the ancient people. And the things that are coming and shall come, let them show these to them.
Do not fear, nor be afraid; have I not told you from that time, and declared it?
You are My witnesses. Is there a God besides Me? Indeed there is no other Rock;
I know not one.’”
