John 13:19
I am telling you this now, [even] before it happens, so that when it does happen, you will believe that I am [the Messiah].
Acts 15:18
This is what the Lord said when He predicted these things long ago.'
1 Peter 1:10-12
The prophets [of old], who spoke of this salvation, asked about and searched diligently concerning the unearned favor [God provided] for you people.
2 Peter 1:19-21
And we have the message of the prophets [confirmed to us] as more certain [than ever]. So, you will do well to pay careful attention to it, as [you would] to a lamp in a dark place, until the day dawns and the morning star rises in your hearts [Note: This probably refers to the beginning of the Gospel age, when people would become enlightened to its message].
