"Through faith" is NOT a one & done.
IF it were so, there would be no falling away, no apostasy of the church in these last days like the Bible says it is.
1 Corinthians 15:1-4
1 Moreover, brethren,
I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2
By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how
that Christ died for our sins according to the scriptures;
4 And that
he was buried, and that
he rose again the third day according to the scriptures:
That's the Gospel, and nothing else. Yes, it is a "one & done" contrary to anything else anyone may add to it. The claim that Paul gave only part of the Gospel, Peter gave some, James gave...etc., that is utterly bankrupt, for it assumes those men were guilty of omissions. They spoke precisely what was for those people at that time, with Paul having spoken what it still for us today.
If you think that you can lose your salvation, then you must also claim Holy Spirit has a weak grasp upon all whom He sealed on the basis of faith alone:
2 Corinthians 1:22
Who hath also sealed us, and given the earnest of the Spirit in our hearts.
Ephesians 1:13
In whom ye also trusted, after that ye
heard the word of truth, the gospel of your salvation: in whom also after that
ye believed,
ye were sealed with that holy Spirit of promise,
It can't get any more clearer than that.
So, please discuss your understanding of those who fail to place their faith in the accomplished work of Christ in these last days. If true believers fall into apostacy, what does scripture, once again, say about that?
2 Timothy 2:13
If we believe not, yet he abideth faithful: he cannot deny himself.
So, any work the Lord does within us is a completed work, sealed by His Holy Spirit, unto...what?
Even if those within the body of Christ deny Him, what will His denial of those believers entail? Most assume loss of salvation, even though the text absolutely does not support that claim. Denial when standing before Him to be judged for our reward, yes, He will deny those as well who denied Him, but that is not a judgement for salvation, but rather reward. Peter denied Christ three times in the evening of His having been taken into custody. What of him? Will we expect to see him burning in Hell for His denials?
This is what's so systemic within churchianity, the teaching of falsehoods that contradict scripture in such glaring disregard for the text and what it says. How many have you ever known who once truly believed in what Christ accomplished, and then denied and walked away from Him? How do you know they were ever saved to begin with? How do you know they will lose their salvation? How do you know where they will stand in their hearts when taking their last breath? All the wild assumptions so many people claim as if they were the ones sitting in the place of God to judge another's eternal salvation...that's just evil; something we should all avoid.
We should minister the joy and peace that we have in Christ by grace through faith. This idea that anyone has the power of Deity to add to his or her salvation, and to somehow maintain it through self effort of works, that's a doctrine of demons, not something found in scripture.
