Acts 20:20

[David]

You know that I did not hold back anything that would be of help
to you as I preached and taught in public and in your homes.

Acts 20:20 Good News Translation

[David]

Apokatastasis (alternately apocatastasis from Greek: ἀποκατάστασις; literally, "restoration"
or "return") is the teaching that everyone will, in the end, be saved. It looks toward the
ultimate reconciliation of good and evil; all creatures endowed with reason, angels
and humans, will eventually come to a harmony in God's kingdom. It is based on,
among other things, St. Peter's speech in Acts 3.21 ("Christ Jesus who must
remain in heaven until the time of the final restoration of all things
χρόνων ἀποκαταστάσεως πάντων") and St. Paul's letter to
Timothy in which he says that it is God's will that
all men should be saved (1 Timothy 2.4). O.W.
   
The Greek word [Apocatastasis] appears in the book of Acts.

"For he must remain in heaven until the time for the final
[restoration] of all things, as God promised long ago
through his holy prophets." Acts 3:21
