1 Be strong ye brethren in the Lord!
Ye children of the light,
And be ye evermore prepar'd,
Your enemies to fight.
2 put on the armour of your God,
The victory to gain;
We wrestle not with flesh and blood,
As are the sons of men.
3 But we must have a constant war,
Whilst we dwell here below;
With Gods and princes of the air,
And all of Satan's crew.
4 O! let us ever watch and pray
And guard on ev'ry hand;
Be ready for the evil day,
And able to withstand.
5 Be sure to stand and never yield:
Move not in any wise;
But stand your ground and gain the field:
Likewise the heav'nly prize.
6 The only weapons we can have
To fight our greatest foes:
Are they which the Almighty gave
For christian men to use.
7 His holy word and living faith,
And the bless'd spirit's aid!
Are weapons which the christian hath
To make his foes afraid.
