17:38 The principalities and powers of heaven are watching the warfare which, under apparently discouraging circumstances, God's servants are carrying on. New conquests are being achieved, new honors won, as the Christians, rallying round the banner of their Redeemer, go forth to fight the good fight of faith. All the heavenly angels are at the service of the humble, believing people of God; and as the Lord's army of workers here below sing their songs of praise, the choir above join with them in ascribing praise to God and to His Son.
