Have You Vowed to Serve the Lord?

Have you vowed to serve the Lord,
'Neath His banner ever fighting?
Flee the evil of this world,
Satan and his power smiting;
Till the victor there shall be,
Waving palms of victory,
Waving palms of victory.

Thus our duty is made plain,
Trusting and in God abiding.
Faithful to thy Lord remain;
Till your eyes in light beholding,
See prepared there for the blest
Shining crowns of righteousness,
Shining crowns of righteousness.
--Zion's Harp #105 vs. 4-5
