The Greek verb apokathistēmi means to restore to a former state, to reestablish, to bring back, to put back in place. In medical usage, it described healing — restoring a body part to full function. In political usage, it described the restoration of exiles or a kingdom.
The disciples' question to the risen Jesus — 'Lord, are you at this time going to restore (apokathistaneis) the kingdom to Israel?' (Acts 1:6) — reflects the deep biblical longing for restoration rooted in this word. Jesus does not rebuke the expectation of restoration but redirects the timing. Acts 3:21 anticipates the apokatastasis (G605) — 'the restoration of all things' — promised by the prophets. Jesus' healings are physical enactments of this word: withered hands restored (apekatestathē, Mark 3:5), sight returned, the lame walking. Each healing was a down payment on the coming total restoration of all creation (Romans 8:19-23).
