John Piper says in the Appendix of A God Entranced Vision
of All Things: The Legacy of Jonathan Edwards:

As a hell-deserving sinner I never could have dreamed of
spending eternity with God in ever-increasing joy in the
ever-increasing revelation of God himself. All I could
expect was destruction and misery. But wonder of wonders,
"Christ also suffered once for sins, the righteous for the
unrighteous, that he might bring (me) to God" (I Pet. 3:18).
