Psalm 72
God's kingdom, is where God is and reigns as king, and where those in God’s kingdom enjoy God’s blessing and rule. Through faith in Jesus Christ we are part of this kingdom even now, but the kingdom has not yet come in all its glory. For at the moment we still live in a time where many people reject God as King, a world still under the curse of sin. One day, however, the kingdom will come in all its glory with the return of Christ.
Psalm 72:1–20 is a song which testifies to the wonders of life in the kingdom, a song that makes us long for the day when Christ returns to rule over a new heaven and earth. Given Peter’s focus on the return of Christ, this would be an appropriate song to sing.
8 But do not overlook this one fact, beloved, that with the Lord one day is as a thousand years, and a thousand years as one day.
