1 Peter 3:20
These people had disobeyed [Noah's preaching, See II Pet. 2:5] back when God's patience waited [for them to repent, See Gen. 6:3], during the days of Noah, when the ship was being constructed. It was by that means [i.e., the ship floating them to safety through the Flood waters] that a few persons, eight of them, were saved [from destruction] through water.
2 Peter 3:9-10
The Lord is not slow about keeping His promise, like some people are, but is [simply] being patient with you, since He does not want anyone to be destroyed, but He wants everyone to repent [i.e., change their hearts and lives].
2 Peter 3:15
And consider [that] the patience of the Lord means [further opportunities for] salvation, [just] as our dearly loved brother Paul also wrote to you, using the wisdom given to him by God.
Revelation 2:21
And I gave her time to repent, but she refused to repent of her sexual immorality.
