This is not what I asked about. The statement in 643 was “We know we are saved because we can look inward and realize that we believe”. We surely CAN look inward, and we should, for example, in order to prepare for confession. We can also recognize that we believe the message of the Church, including, of course, the Gospel at its center. But where does the scripture recommend that we look inside to gain an assurance of our salvation? I can show many directly relevant passages where we are encouraged to look at our works in order to see our faith, but I was wondering if there was something about proving one’s faith by introspection.
Navel-gazing our way to salvation? Wow, you may have come up with yet another hook for a televangelist show. Choices - Oral Roberts climbing a tower that God will kill him in unless you send him 7 million dollars - Jimmy Swaggart crying about how prostitutes tore a hole in his jogging suit - Kenneth Hagin unctuously prattling about saving the Jews - W. Herbert Armstrong beetling on about space aliens invading Earth in Revelation - and Alex making millions off navel-gazing as a path to salvation. I suppose that it beats glass looking or hat gazing. This way, you don't have to buy the hat or glass...
Thank you for your reply, dear brother in Christ!
