This hymn, written in 1905 by the Methodist lay leader Leila Morris, might give you some inspiration. You certainly won't find it in the present-day United Methodist Church hymnal.
THE FIGHT IS ON
The fight is on, the trumpet sound is ringing out,
The cry “To arms!” is heard afar and near;
The Lord of hosts is marching on to victory,
The triumph of the Christ will soon appear.
Refrain:
The fight is on, O Christian soldier,
And face to face in stern array,
With armor gleaming, and colors streaming,
The right and wrong engage today!
The fight is on, but be not weary;
Be strong, and in His might hold fast;
If God be for us, His banner o’er us,
We’ll sing the victor’s song at last!
The fight is on, arouse, ye soldiers brave and true!
Jehovah leads, and victory will assure;
Go buckle on the armor God has given you,
And in His strength unto the end endure.
Refrain
The Lord is leading on to certain victory;
The bow of promise spans the eastern sky;
His glorious Name in every land shall honored be;
The morn will break, the dawn of peace is nigh.
Refrain
I tried to find a song in the new hymnal that I could sing at a funeral (was asked to sing when I came in) and I looked through it and was astounded that I couldn't really find anything I knew. I don't even think they have Onward Christian Soldiers in it anymore. bye bye Methodists...
