I actually wrote this a long time ago.

Rallying followers deep,
Raising our efforts high,
Advent’ring mountains so steep--
To search our battle cry.

Sound above the wind of rains
And the roars of passersby,
Marking our distant pains--
Give us our battle cry.

Brought through without a thought
By Him who once did die,
With blood now we are bought--
Listen: our battle cry.

Passions flowing through our veins,
By Love now we will fly
With strength over the plains--
Now this our battle cry.

Sing loud our song of Psalms!
So that you will imply,
“Shine you and thus be calm”--
Hear this our battle cry.
