1 How do we start to touch the broken hearts,
the barren lives, the lonely and bereaved?
In Jesus' name we shall go forth:
His healing power for ever is the same!
That the world may believe
that the world may believe
that the world may believe in you!

1A How do we start to touch the broken hearts,
the barren lives, the lonely and bereaved?
Lord, in your name we shall go forth:
your healing power for ever is the same!
That the world may believe
that the world may believe
that the world may believe in you!

2 We shall proclaim the love of Jesus Christ
a man of sorrows, yet a man divine;
his worthiness, his loveliness,
his faithfulness for ever we will sing!
That the world may believe
that the world may believe
that the world may believe in you!

3 And so we go into a lonely world
where fear reigns and sorrow fills the air;
yet, as we go your Spirit comes
your cleansing power you give us to share!
That the world may believe
that the world may believe
that the world may believe in you!
