The beginning verses in this chapter sum up the exhortations in previous chapters. Christ is our example for all of our actions as believers with a new life in the Spirit.
An order for nations in the millennium follows: Jesus Christ was the minister of Israel to confirm the promises made to the fathers. This was rejected by the nation, thereby letting the Gentiles in.
Gentiles believed and were brought into the assembly with the Jewish remnant at Pentecost.
In the coming kingdom, Gentiles will be blessed with Israel.
In that day multitudes without number, of saved Gentiles, will praise the Lord with Israel.
The root of Jesse (Christ) will rise to reign over the Gentiles, and they will trust in Him.
Should some consider themselves to be something, full of goodness, knowledge, and able to admonish, the apostle says, "I have written the more boldly unto you in some sort, as putting you in mind, because of the grace that is given to me of God." The Apostle Paul was not taken up with self, or his own merits, but rather with Christ and His grace that caused him to act in love in his service to Christ.
Paul in his ministry to the Gentiles would set them up as a sacrifice to God to be acceptable to Him by the Holy Spirit. His ministry was widespread; those of the Gentiles will see and understand.
The apostle spoke of his proposed journey to Jerusalem to take the Gentile offering of love and fellowship (money), carried personally by Paul and his companions. The Gentiles had benefits from the Jewish blessings. Now it is the Gentiles who return the love and a gift to the Jews. No doubt there was a famine that brought this about. The apostle desired the prayers of the saints.
