No, it isn't possible because those who become saved, become saved, not by what they have done or will do, but because they have been covered by Christ - by His offering and His sacrifice - as He alone is the Savior - it is not within man's power to be his own savior nor his own un-savior. You do believe that Christ alone is the Savior, don't you?
I'm not going to go through every verse you posted to refute them, but I believe they can generally be summed up and answered with the following verses - that it is possible to believe for a while and sill yet fall-away. This is because that type of belief is an intellectual belief which originates from the mind of man, not a belief that accompanies salvation - a belief placed into the spiritual heart of man, which is how a true belief enters and resides within man. In addition, true belief is not what saves anyone, it is a free gift as the result of salvation (which also is a free gift) given by an exceedingly merciful and gracious God through Jesus Christ the Savior - it is not by man.
You won't explain MY verses,,,,but I'll explain YOURS.
This is because it's very easy to and apparently mine are not.
It would have been nice, however, if you DID take the time to explain why they don't mean what i think they mean.
however...we'll move on with YOURS.
(in an attempt to avoid playing verse ping pong).
[Luk 8:12-15 KJV]
12 Those by the way side are they that hear; then cometh the devil, and taketh away the word out of their hearts, lest they should believe and be saved.
13 They on the rock [are they], which, when they hear, receive the word with joy; and these have no root, which for a while believe, and in time of temptation fall away.
14 And that which fell among thorns are they, which, when they have heard, go forth, and are choked with cares and riches and pleasures of [this] life, and bring no fruit to perfection.
15 But that on the good ground are they, which in an honest and good heart, having heard the word, keep [it], and bring forth fruit with patience.
You might have missed this from a prior post, but I believe that it conclusively proves that once saved always saved because it is God Himself who has clearly made Himself its guarantor.
Well, let's see if Luke stating what Jesus taught is presenting the idea of OSAS.
Those in Verse 12 hear the word but never receive it.
Those in Verse 15 are the good soil. They hear the word an KEEP IT. They bring forth fruit.
Now....
Verse 13.....These receive the word WITH JOY. This means they HEARD the word and received it. It planly states this.
Jesus Himself is stating that THEY BELIEVED FOR A WHILE. A believer is a saved person. They believed for A WHILE.
and then they FELL AWAY.....due to temptation.
There are different reasons why a person might fall away...
the fact is that it is possible.
Paul confirms this many times, as do the other writers.
Hebrews 6:4-6
4 For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit,
5 and have tasted the good word of God and the powers of the age to come,
6 and then have fallen away,
Verse 14...These are those that hear but allow the cares of the world to hold them back.
Jesus said that if we wish to follow Him...
we must not look back.
Luke 9:62
62 But Jesus said to him, "No one, after putting his hand to the plow and looking back, is fit for the kingdom of God."
So we can see that Jesus and other writers do not support the concept of OSAS but warn us that this is possible.
Notice in v4 (below) - that salvation is by inheritance and reserved in heaven for those whom He has chosen to salvation. If reserved by God, then it must come to fruition exactly in that way - with no changes or exceptions to it permitted. Notice in v5 that they are "kept by the power of God" (not man), "unto salvation", the final salvation of the last day.
Did you say that God CHOOSES who will be saved?
Is it based on something?
Man does not lose his free will when he becomes saved.
Nothng MUST come to fruition.
God has done His part...
now it is up to us to do our part....
obey Him.
Not let temptation take us away from Him as in verse 13 about the sower.
[1Pe 1:3-5 KJV]
3 Blessed [be] the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
We all agree.
4 To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
5 Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
Correct.
Notice that we are KEPT BY FAITH.
If we lose Faith...
we lose salvation.
Also, you posted a verse that does not help you too much.
It states
THROUGH FAITH
UNTO SALVATION READY TO BE REVEALED IN THE LAST TIME.
Our salvation will be revealed at the end.
This is precisely because we may...along the way....in our lifetime....somehow decide we no longer wish to serve God.
We cannot be 100% certain right now that we will still have FAITH when we die.
I believe this in confirmed with the following verses - that once the testator (Christ) died, no changes to His will and testament - either to add to it, or to remove from it - were permitted.
[Heb 9:15-17 KJV]
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions [that were] under the first testament, they which are called might receive the promise of eternal inheritance.
16 For where a testament [is], there must also of necessity be the death of the testator.
17 For a testament [is] of force after men are dead: otherwise it is of no strength at all while the testator liveth.
The above is just stating that Jesus had to die in order for the New Covenant to become valid.
I'm sure you'll agree that we must be IN the NC
if we wish to be a part of it.
Since God demanded obedience in every Covenant of His....
This obedience that is required has not been rescinded.
It is still obligatory for man to obey God.
Even though the NC is unilateral.
