Judgement Seat of Christ

Matthew 10:12 But going into the house you shall greet it, 13 and indeed if the house should be worthy, let your peace come upon it, but if it should not be worthy, your peace must return to you. 14 And whoever would not receive you nor hear your words, going out of that house or city shake off the dust from your feet. 15 Truly I say to you, it shall be better for the land of Sodom and Gomorra in the day of judgment than for that city!

This does not mean that the Canaanites of Sodom and Gomorra are going to be resurrected and judged. Firstly, it cannot even be established that the residents of those cities at the time of Abraham and Lot were even all Canaanites. Rather, it states that for those who reject the Gospel of the Kingdom, it will be worse for them in the judgement than it was for Sodom and Gomorra.
