George Herbert - The Holdfast

I threatened to observe the strict decree
Of my deare God with all my power and might:
But I was told by one, `It could not be;
Yet I might trust in God to be my light.'

`Then will I trust,' said I, `in Him alone.'
`Nay, ev'n to trust in Him, was also His:
We must confesse that nothing is our own.'
`Then I confesse that He my succour is.'

`But to have nought is ours, not to confesse
That we have nought.' I stood amaz'd at this,
Much troubled, till I heard a friend expresse
That all things were more ours by being His:

What Adam had, and forfeited for all,
Christ keepeth now, Who cannot fail or fall.

George Herbert
