No, sir, you did not. Your whole premise is based on a faulty understanding of the present tense. It does NOT mean continuous action for the rest of eternity, as I proved from other words that both Jesus and Paul used in expressing believing in Christ for salvation. How do you explain their use of the aorist tense, which is a point in time action, without any regard for duration of time?
[Deleted inappropriate comment. WIP] So I am guilty as charged.
Jesus tells us that those to whom He gives eternal life (which is WHEN they believe) they WILL NEVER PERISH.
And you haven't provided any verse that teaches that salvation or eternal life exists only as long as one continues to believe. Your faulty premise is that one must continue to believe in order to continue to be saved. What verse says that? It's not Jn 5:24, which is what you think it means.
If that were true, then neither Jesus nor Paul would EVER have used the aorist tense for "believe" when speaking about getting saved.
Jesus said this: “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 and be saved. Luke 8:12 The word 'believe' is aorist. Point in time.
13 “Those on the rocky soil are those who, when they hear, receive the word with joy; and these have no firm root; they
believe for a while, and in time of temptation fall away. How do you explain WHY Jesus used the present tense along with "for a while"? How does that make sense to your understanding of the present tense?
They said, “Believe in the Lord Jesus, and you will be saved, you and your household.” Acts 16:31
Paul used the aorist tense here.
Further, consider this word from Jesus:
but
who ever drinks of the water that I will give him
shall never thirst; but the water that I will give him will become in him a well of water springing up to eternal life.” Jn 4:14 The word "drinks" is aorist tense.
I see a parallel between what Jesus said in Jn 4:14 and 10:28. Those who "drink of the water that I will give him" WILL NEVER THIRST is the same as saying "to them I give eternal life and they WILL NEVER PERISH.
Since Jesus used the aorist tense for "drinks", one cannot claim that salvation is based on continuous action.
Salvation is based on a point in time action of placing one's faith in Jesus Christ for eternal life. At that moment, they HAVE eternal life, and they WILL NEVER PERISH. A promise from Jesus.
