What does it mean that Christ sings of God's mercies?

In Psalm 89, Christ is depicted as singing of the mercies of the Lord, illustrating His role as both our mediator and the model for worship. This singing demonstrates His joy and confidence in God's faithfulness and serves as an encouragement for the Church to join Him in praising God. In Hebrews 2:12, we see this connection where Christ proclaims God’s name and sings in the midst of the congregation. This not only underscores the relationship between Christ and His people but also reminds believers that their worship is rooted in the acknowledgment of God’s mercies and faithfulness.
