What does the Bible say about damnation and deliverance?

In 2 Peter 2, we learn that damnation is not arbitrary but is a just result of rejecting God's sovereignty and living in sin. Specifically, the chapter highlights that certain individuals and their followers shall be certainly damned for promoting damnable heresies and denying their creator. These heretics are described as self-willed and presumptuous, walking after the flesh, leading many to perish alongside the angels who fell and the ungodly of Noah's time. On the other hand, deliverance is illustrated through Noah and Lot, who, despite their imperfections, were deemed righteous by God and were delivered from judgment. Therefore, while all men face condemnation for their sin, God is able to save those He has chosen, regardless of their past decisions or failures.
