Can you be obedient (Hymn 657)

Verse 1: Can you be obedient To the Lord of all, Though the earth should totter, Though the heav'ns should fall? Face e'en a disaster With a faith-filled heart, Knowing naught can harm him Who with Christ will start? Verse 2: Can you be obedient To the Lord you serve, Never even flinch, friend, Never even swerve; Though your next step onward Seem to lead to death? Can you then obey Him Without bated breath? Verse 3: Can you trust your Leader When He bids you go Right into a battle With a mighty foe? Can you step up briskly And with joy obey? Can you fight the battle, Till the end of day? Verse 4: Can you? Then beloved, Christ just waits for you; Listen for His orders, Glad His will to do; Then when soldiers muster At the set of sun, And your name is mentioned, Christ will say, "Well done."
