If God's loving-kindness is "from everlasting to everlasting," will not His children share in it for as long? The psalm has no articulate doctrine of a future life; but is there not in that thought of an eternal outgoing of God's heart to its objects some (perhaps half-conscious) implication that these will continue to exist? May not the psalmist have felt that, though the flower of earthly life "passed in the passing of an hour," the root would be somehow transplanted to the higher "house of the Lord," and "flourish in the courts of our God," as long as His everlasting mercy poured its sunshine? We, at all events, know that His eternity is the pledge of ours. "Because I live, ye shall live also."
From ver. 19 to the end, the psalm takes a still wider sweep. It now embraces the universe. But it is noticeable that there is no more about "loving-kindness" in these verses. Man's sin and frailty make him a fit recipient of it, but we do not know that in all creation another being, capable of and needing it, is found. Amid starry distances, amid heights and depths, far beyond sunrise and sunset, God's all-including kingdom stretches and blesses all. Therefore, all creatures are called on to bless Him, since all are blessed by Him, each according to its nature and need. If they have consciousness, they owe Him praise. If they have not, they praise Him by being. The angels, "heroes of strength," as the words literally read, are "His," and they not only execute His behests, but stand attent before Him, listening to catch the first whispered indication of His will. "His hosts" are by some taken to mean the stars; but surely it is more congruous to suppose that beings who are His "ministers" and perform His "will" are intelligent beings. Their praise consists in hearkening to and doing His word. But obedience is not all their praise; for they, too, bring Him tribute of conscious adoration in more melodious music than ever sounded on earth. That "choir invisible" praises the King of heaven; but later revelation has taught us that men shall teach a new song to "principalities and powers in heavenly places," because men only can praise Him whose loving-kindness to them, sinful and dying, redeemed them by His blood.
Therefore, it is no drop from these heavenly anthems, when the psalm circles round at last to its beginning, and the singer calls on his soul to add its "little human praise" to the thunderous chorus. The rest of the universe praises the mighty Ruler; he blesses the forgiving, pitying Jehovah. Nature and angels, stars and suns, seas and forests, magnify their Maker and Sustainer; we can bless the God who pardons iniquities and heals diseases which our fellow-choristers never knew.
