Romans 9:22
What if God [did] patiently put up with people who deserved His wrath and [who were] ready for destruction, even though He was willing to demonstrate His wrath and power?
2 Peter 2:1
But just as there were false prophets among the people before, there will also be false teachers among you [Christians]. They will privately teach harmful doctrines that destroy people [spiritually], by even denying [that Jesus is] the Master, [and thereby] destroying themselves quickly.
