Depends on what type of believer. The nominal, shallow, or lukewarm believer can indeed fall away (Luke 8:13). However, the Christian with the fear of the LORD (Jeremiah 32:38-40, Psalms 19:9) who has a heart faith that is unto righteousness, cannot
Wrong again. Paul said that he himself could fall and not get to Heaven - "... lest after preaching to others I myself should be disqualified" (1Cor 9:27).
And Hebrews 3:14 says, "For we have become partakers of Christ IF WE HOLD FAST the beginning of our assurance firm until the end" (Hebrews 3:14)
Furthermore, none of us can judge ourselves saved - "I do not even judge myself. I am not aware of anything against myself, but I am not therefore acquitted. It is the Lord who judges me. Therefore do not pronounce judgement before the time, before the Lord comes, who will bring to light the things now hidden in darkness and will disclose the purposes of the heart. Then every man will receive his commendation from God." (1Cor 4:3-5)
What on earth is a “heart faith”?
The blood of Jesus does indeed sanctify
The blood of Jesus does indeed sanctify, but “sanctify” does not mean “you are certain to be saved”. One of the verses you quote - Hebrews 10:29 - makes this very clear: “How much worse punishment do you think will be deserved for the man who has spurned the Son of God, and profaned the blood of the covenant BY WHICH HE WAS SANCTIFIED, and outraged the Spirit of grace? … It is a fearful thing to fall into the hands of the living God” (Hebrews 10:29-31). Clearly, this man was sanctified by the blood of Jesus by was not saved.
That makes no sense at all. What He is saying is that Christian believers who say to Him Lord, Lord, and do not do what He says are not true Christians at all...He literally has never known them.
Listen to what you’re saying - someone can become a Christian and yet Jesus literally doesn’t know who they are! Christ ”lives” in every Christian (Gal 2:20), so how on earth can Christ live in someone and yet not know them?
Furthermore, how did these Christians get the power to prophesy, cast out demons and perform miracles if Jesus never knew them?
You do understand that Jesus is God? There is only one mediator between God and man.
The Scripture say there is one mediator between God and man - “the MAN, Christ Jesus”. Which Scripture says there can be no mediator between mankind and the MAN, Christ Jesus.
You should take a wild look at some Protestant churches...you won't find the same apostasy there
Oh, you mean like the Protestant churches that condone homosexuality, have homosexual ministers and marry homosexuals? LOL!!! Not the mention the fact that all Protestant churches are based on a solid tradition of heresy.
There are many millions of devout, faithful and uncorrupted Catholics who reflect the holiness of the one, true Church. They are the “living water” of Catholicism.
