WARNING: LONG POST
B.L.U.F. As long as you believe in Jesus and submit to His Lordship, you are saved. When you no longer believe in Jesus, you loose your salvation. The book of life is written in pencil and the only person who can erase it is you. Nobody else can do that and God (although able to) will not.
Please provide clear Scripture that teaches that those who no longer believe are no longer saved? The claim keeps being made, yet without any Scriptural support.
For people who believe that “once saved, always saved” I rhetorically ask: how do you relate your beliefs to Matthew 13: 20-21? If a man cannot lose his salvation then why would Jesus say: “When trouble or persecution comes because of the word, he quickly falls away”?
The answer is easy. The phrase "falls away" refers to belief, not being saved.
The key to how we are saved is in John 3:16:
“For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.” [NIV]
I understand that the word ‘believes’ in the Greek is an on-going verb (this is not so easy to determine because Greek is a contextual language). It really says that unless we keep on believing in Him we will perish and not have everlasting life. We are saved by Grace as long as we keep on believing in Him. Let’s check another Scripture.
This view ignores, or is ignorant of, all the verses that speak of believing in the AORIST TENSE for salvation. That tense ignores duration of the action. It is like a snapshot of an action, rather than a video of it.
Paul used the aorist tense in his answer to the jailer's question: "what must I do to be saved?". "Believe (aorist) on the Lord Jesus Christ, and you will be saved".
Jesus Himself used the aorist tense in Luke 8:12 - “Those beside the road are those who have heard; then the devil comes and takes away the word from their heart, so that they will not believe (aorist) and be saved."
And Paul used the aorist tense in Rom 10:9 - that if you confess with your mouth Jesus as Lord, and believe (aorist) in your heart that God raised Him from the dead, you will be saved
So, it is clear that the Scriptures teach that one IS SAVED from a point in time belief in Christ.
On-going belief is NOT required in order to either get saved, or stay saved.
So how does the Holy Spirit cause someone to believe?
So, the Holy Spirit DOESN'T cause anyone to believe.
Rom 10:10 says that man "believes from the heart". To put one's trust or faith in someone or something is a choice to make.
In conclusion, a Christian can loose their salvation.
In fact, Scripture teaches otherwise.
Rom 11:29 says that the gifts and calling of God are irrevocable.
Rom 6:23 says that eternal life is a gift of God.
Jesus taught that those who believe HAVE (present tense) eternal life in John 5:24.
Jesus also taught that those He gives eternal life WILL NEVER PERISH in John 10:28.
Nobody can take your salvation away.
When Jesus said that "no one can snatch the believer out of God's hand", He was actually saying "no person". Since the believer is a person, He was including even the believer himself.
Further, there are NO VERSES that teach that we can give it away.
But when doubt grows, faith is destroyed. When faith is destroyed, we no longer believe. When we no longer believe, we loose our salvation.
As I've just proven, this claim is unsubstantiated in Scripture.
Scripture teaches the exact opposite. Those who have been given eternal life WILL NEVER PERISH.
That promise is NOT believed by some Christians. They have
no faith in what Jesus promises regarding those He gives eternal life to.
