If anything is lacking in any of them, one may hope that God will supply the deficiency by the power of His Holy Spirit. He guides into all truth and consoles in everything with the highest hope. By this hope all our present shortcomings are covered, and all the perfections and gifts of God, abundantly given to us, are brought to fulfillment.
The Apostle confirms by many prophecies that the Gentiles were called by God through mercy. According to St. John Chrysostom, in them he "brings everything forward as proof that all must be united and glorify God." At the same time, he wishes "to humble the Jew, so that he will not exalt himself over the Gentile. Because all the prophets call the Gentiles to the glorification of God." He also wishes "to teach modesty to the Gentile, showing that he is bound to give greater thanks to God."
At the conclusion of his exhortation, the Apostle prays to the Lord Himself. He asks Him, by the power of the Holy Spirit, to fill the Romans with the spirit of joy, peace, and all-perfect hope.
Concerning this prayer, Bishop Theophan observes: "This prayer, while verbally attached to the prophet’s words just cited, corresponds in its content to the whole preceding section, chapters 14 and 15. The object of the prayerful good wish is abundance of hope. For this to exist, he wishes the heart to be filled with joy and peace. Faith is indicated as the source of these gifts. Faith gives birth to joy and peace. Joy and peace multiply hope. All this comes about by the power of the Holy Spirit. The power of the Holy Spirit engenders spiritual life. It sustains it and leads it to perfection. From it come all movements and changes in the spiritual life. In view of the Romans’ condition, the Apostle especially wishes them joy and peace. When these are present, the minor differences in convictions of which he speaks will no longer have the harmful consequences that now arise from them. Joy and peace will suppress every quarrel, division, and estrangement, and will no longer allow them to arise."
Through hope in the Lord and His Christ, everything will be ordered in the best way for our good and salvation.
