Now, how can I be so sure of that? you might wonder. It's a question I often ask myself. How can I know that my own selfishness and pride will not foster bitterness and divisiveness between us and ultimately lead to a divorce?

*I am aware that the passages from Jeremiah and Ezekiel were first spoken to Israel in her exile. But these promises are certainly not for Jews alone; they belong to the "everlasting covenant" of grace into which the entire worldwide church has been engrafted through faith in Christ and his gospel. In a nutshell, the apostolic message of the New Testament is that the promises of deliverance and kingdom given to Israel were now being fulfilled through the Messiah, and they have been opened up to all nations, that they too might share in Messiah's benefits. Hence Paul can call the Gentile Galatian church "the Israel of God" (Galatians 6:15-16; cf. Ephesians 2:12-13; 3:6).
