2 Peter 3:8-9

Amplified Bible

⁸ Nevertheless, do not let this one fact escape your notice, beloved, that with the Lord one day is like a thousand years, and a thousand years is like one day.^{(A) 9} The Lord does not delay [as though He were unable to act] and is not slow about His promise, as some count slowness, but is [extraordinarily] patient toward you, not wishing for any to perish but for all to come to repentance.
