Almighty God, Who hast enabled Thy faithful soldiers and servants to play the man, to endure hardness, to love mercy, to fight the good fight of faith, and to refuse no service in the Name of Christ: grant unto us whom Thou hast called to serve under our Saviour’s banner a single heart to spend and to be spent for Thee and for those whom He has loved even unto death; through the same Jesus Christ our Lord.
