I know not what my health will be,
But this I know full well —
Sufficient it will be for me
To do my Lord's work well.

I know not what that work will be,
But this I fully know:
That I'll have opportunity
For tasks that God doth show.

I know not where God's choice may be
For me my years to spend,
But this I know — He'll be with me
Until those years shall end.
