The Holdfast, by George Herbert

"The Holdfast" by George Herbert, from The Temple (1633):

I threatened to observe the strict decree
          Of my deare God with all my power & 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.
