A prayer for unending praise of God

Day and night, we confess your name, O Lord, and proclaim your glory. In wisdom you have made all things and by your Spirit you sustain them. From sunrise to sunset you reveal your majesty, speak peace to our hearts and protect your people. With unending praise, with all your saints, we rejoice in the gift of salvation.
