Sustaining Grace

Speaking of being made to stand by the grace of God - I once read an sermon by C. H. Spurgeon called "Final Perseverence", in which he quoted the lines below. They were unattributed, but I believe they are from a hymn by Charles Wesley. I have been unable to find the exact title.

See a stone that hangs in air,
See a spark in ocean live!
Kept alive with death so near,
I to God the glory give.

These words have been a blessing indeed to me. For the entire hymn, read the post below.
