Here is the voice of my father for 4 minutes on how final salvation is contingent on perseverance, and yet eternal security and assurance are possible. It comes from an exposition of Colossians 1:21-23.

And you, who once were alienated and hostile in mind, doing evil deeds, he has now reconciled in his body of flesh by his death, in order to present you holy and blameless and above reproach before him, if indeed you continue in the faith, stable and steadfast, not shifting from the hope of the gospel that you heard, which has been proclaimed in all creation under heaven, and of which I, Paul, became a minister.

This is from the overflow of what I have been reading and listening to in preparation for the pastors’ conference where I plan to give a biographical study of my father.
