Psalm 21
Given Peter’s focus on the return of Christ, it would be a good idea to sing a psalm that likewise looks forward to Christ’s return in glory. Psalm 21:1–13 is one such song. It anticipates the day when God’s King is publicly crowned to demonstrate his worldwide rule (Psalm 21:3), granted eternal life (Psalm 21:4), and given great glory (Psalm 21:5). Above all, the King’s joy comes from reigning in intimate fellowship with God his Father (Psalm 21:6); his victory over death being the fruit of his faith in the love of the Most High (Psalm 21:7). The King’s victory also results in total destruction of all enemies, a burning up in righteous wrath of those who stand against God (Psalm 21:8–12).
The dominant note in Psalm 21 then is the joy that comes from a certain confidence in the victory of God’s King and the final return of Christ in glory. We do not see Christ now; he is seated at the right hand of the Father. Yet he has conquered death, his resurrection guaranteeing our salvation (1 Peter 1:8–9). And so we can look forward to his return without fear.
1 But false prophets also arose among the people, just as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Master who bought them, bringing upon themselves swift destruction.
