And the heavens shall praise your wonders, O LORD: your faithfulness also in the congregation of the saints.
Read Chapter 89
Augustine of Hippo
AD 430
6. "O Lord, the very Heavens shall praise Thy wondrous works" (ver. 5). The Heavens will not praise their own merits, but Thy wondrous works, O Lord. For in every act of mercy on the lost, of justification of the unrighteous, what do we praise but the wondrous works of God? Thou praisest Him, because the dead have risen: praise Him yet more, because the lost are redeemed. What grace, what mercy of God! Thou seest a man yesterday a whirlpool of drunkenness, to-day an ornament of sobriety: a man yesterday the sink of luxury, to-day the beauty of temperance: yesterday a blasphemer of God, to-day His praiser: yesterday the slave of the creature, to-day the worshipper of the Creator. From all these desperate states men are thus converted: let them not look at their own merits: let them become Heavens, and praise the wondrous works of Him by whom they were made Heavens. ...

Preachers announce the same in the Church, (St. Augustine) "the communion of saints "as none are found out of her society. (Haydock)
