I was just having this conversation with someone else. People do not want to accept the fact that not everyone who believes will enter heaven; there is a human doctrine of "once saved always saved", and that faith alone is sufficient for salvation. While we are indeed saved by faith; even demons believe and tremble. We must demonstrate our faith by living it out: sincere repentance and good works. Certainly those people who cast out demons in Jesus name did in fact truly believe in Him, but accepting the mere facts is not enough. The fact that Jesus Christ is the only begotten son of God, that he was crucified for the forgiveness of sins, that he is resurected and seated at the right hand of the Father... acknowledging that fact does not mean you love God, and have given your life to Him, and are born-again and saved. Acknowledging that fact is acknowledging that 1+1=2. Even demons believe, and tremble.
Not every place in the scriptures where it uses the word believe is it talking about saving faith. Quoting one verse hardly ever proves anything absolutely. We need to consider the whole council of God.
I think this one is pretty easy personally, I see no reason to make it harder than necessary:
John 6
26 Jesus answered them, "Truly, truly, I say to you, you are seeking me, not because you saw signs, but because you ate your fill of the loaves. 27 Do not work for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you. For on him God the Father has set his seal." 28 Then they said to him, "What must we do, to be doing the works of God?" 29 Jesus answered them, "This is the work of God, that you believe in him whom he has sent." 30 So they said to him, "Then what sign do you do, that we may see and believe you? What work do you perform? 31 Our fathers ate the manna in the wilderness; as it is written, 'He gave them bread from heaven to eat.'" 32 Jesus then said to them, "Truly, truly, I say to you, it was not Moses who gave you the bread from heaven, but my Father gives you the true bread from heaven. 33 For the bread of God is he who comes down from heaven and gives life to the world." 34 They said to him, "Sir, give us this bread always." 35 Jesus said to them, "I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst. 36 But I said to you that you have seen me and yet do not believe. 37 All that the Father gives me will come to me, and whoever comes to me I will never cast out. 38 For I have come down from heaven, not to do my own will but the will of him who sent me. 39 And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day. 40 For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day." 41 So the Jews grumbled about him, because he said, "I am the bread that came down from heaven." 42 They said, "Is not this Jesus, the son of Joseph, whose father and mother we know? How does he now say, 'I have come down from heaven'?" 43 Jesus answered them, "Do not grumble among yourselves. 44 No one can come to me unless the Father who sent me draws him. And I will raise him up on the last day. 45 It is written in the Prophets, 'And they will all be taught by God.' Everyone who has heard and learned from the Father comes to me-- 46 not that anyone has seen the Father except he who is from God; he has seen the Father. 47 Truly, truly, I say to you, whoever believes has eternal life.
In this case, when Jesus is using the word believe, he is talking about true saving faith, not just the common meaning of the word believe. We choose to believe many things that we know deep down are not true, like that our government has our best interest at hand, or that our votes in the national elections actually make a difference, etc, etc. This is the common meaning of the word believe. There are places in the scriptures that are speaking very practically which use this meaning. But here, Jesus is redefining what it means to believe (to have faith). No one who has real faith accomplished this on their own. It is a supernatural work of God.
True saving faith (believing) always manifests itself in tangible works, without exception. Works are evidence that a person truly has faith, but they are not the source of that faith. Instead, faith is the source of those works.
Beleiving in Jesus Christ as our personal Lord and Savior is not easy to do, it takes a supernatural work of God. We should not downplay faith by assuming it's common as dirt and something we can fickly decide to exercise however we please, in whomever we please. No one can come to the Son unless the Father draws them, there are no exceptions to this.
So, if we are talking about common belief, what we as humans choose to believe at any given time, then yes one can stop believing in Jesus to save them. If we are talking about how the bible redefines the word, then all who believe in Jesus Christ to save them will be saved by him, without exception. One can certainly be deceived into thinking they are a believer when they are not, I would never disagree with this. This is what is behind the error of what is labelled as OSAS. Praying a little prayer when everyone has their eyes closed is not a free pass to heaven, God must regenerate a mans heart, they must be born again. God does not beckon to little parlor tricks and soulish devices.
We should never downplay saving faith though. IMO
Grace to you,
