Within church history, there have been times when entire peoples have been converted to the faith, almost overnight. One apostle, one incident, and a nation turns to faith. This happened in the islands last century (and we should give thanks to the Anglican Church Missionary Society and the congregationalists, who did the bulk of the work). It entailed considerable risk: some of the Islands were feared, due to cannibalism; others had a history of violence, destroying imperial explorers.
But the first apostle to do this was Peter. There is a tipping point, where a tribe gives up its old gods, when it hears the gospel.
32 Now as Peter went here and there among them all, he came down also to the saints who lived at Lydda. 33 There he found a man named Aeneas, bedridden for eight years, who was paralysed. 34 And Peter said to him, “Aeneas, Jesus Christ heals you; rise and make your bed.” And immediately he rose. 35 And all the residents of Lydda and Sharon saw him, and they turned to the Lord.Acts 9:32-35, ESV
Nobody expects a paralysed man, eight years after his accident, to stand up and walk. Not even superman. We can use robotic walkers, true, but the damage was done. This was a miracle, and miracles are acys of power.
But the greater power is salvation. Choose Christ, and disavow the temptations of this world.
