“Above all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. 4 They will say, “Where is this ‘coming’ he promised? Ever since our ancestors died, everything goes on as it has since the beginning of creation.” 5 But they deliberately forget that long ago by God’s word the heavens came into being and the earth was formed out of water and by water.6 By these waters also the world of that time was deluged and destroyed.” (II Peter 3:3-6)
God is a merciful and loving God. He will forgive those who truly repent no matter how bad they are. However, He will one day punish the entire world and everyone in it who refuses to believe His Word.
