Matthew 7 And Eternal Security

During his recent debate with Ryan Hemelaar, Trent Horn commented:

"Jesus even warns people who claim they will be saved because they call on his name or trusted him, but engaged in grave sin. He says in Matthew 7:21, 'Not everyone who says to me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of my Father who is in heaven.'"

And when advocates of eternal security put forward the idea that an alleged believer who commits apostasy may have never been a believer, that view is often dismissed as absurd, desperate, and so forth.

While Trent ended his citation of Matthew 7 at verse 21, we should go on to verses 22-23. As I noted in a post (not about eternal security) several years ago, "People often associate the thinking behind 1 John 2:19 with the fourth gospel, but some of the same concepts are found in Matthew 7:21-23." In addition to the agreement between such diverse sources as the gospel of Matthew and 1 John, there's also the fact that Judas was involved in so much apostolic work while being "a devil" (John 6:70).

I'm not citing such examples to argue that believers never commit sins that some people consider mortal or never go through lengthy periods of unrepentant sin. They do sometimes (e.g., David).

My point is that the first scenario I referred to not only isn't absurd, desperate, and such, but is even explicitly advocated by multiple Biblical authors in multiple contexts. The Judas material is about one individual, but the other two passages I've cited use the plural. Matthew 7:22 even uses the term "many". So, it isn't just some extremely rare scenario. Furthermore, the Matthew 7 passage has a significant number, variety, and quality of nominally Christian works being done, presumably over a long period of time. Yet, Jesus says he never knew the individuals involved. And 1 John 2:19 puts forward "they would have remained with us" as the normal scenario. John is putting forward perseverance as the norm (as he does elsewhere, in 1 John 5:18, etc.).

Trent refers to "people who claim they will be saved because they call on his name or trusted him". Who claims that you can just "call on his name" in the sense of saying "Lord, Lord" to Jesus and be saved by doing so? And where does Matthew 7:21 say that the individuals involved trusted him in a relevant sense? It doesn't. One of the biggest themes of the gospels is Jesus' commenting on the lack of faith of the people around him, even how small the faith of his closest disciples was at times. We shouldn't be starting with a default assumption that people have genuine faith or even faith of any type, and nothing in Matthew 7:21 justifies the conclusion that people who said "Lord, Lord" without doing the will of God had faith.
