21 And you, who once were alienated and enemies in your mind by wicked works, yet now He has reconciled 22 in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight— 23 if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister. Colossians 1:21-23
Continue in the faith, to remain reconciled to God.
That isn't what the verse either says or teaches.
In v.23 we see a conditional clause, "IF indeed you continue in the faith". So, what happens IF we continue in the faith? The answer is found in the previous verse, "to present you holy, and blameless and above reproach in His sight".
iow, it is ONLY BY continuing in the faith that God can present the believer holy, and blameless and above reproach in His sight. There's no other way.
Faith is the substance of things hoped for...
If we are moved away from the hope of the Gospel, then we are moved away from the salvation that is the hope of the Gospel.
Another misread of Scripture. It doesn't either say or mean what is being claimed here.
The word for "hope" in the Greek means a confident expectation, not a wishful thinking. And those who do not continue in the faith will of course lose their confident expectation. But that isn't the same as losing salvation itself.
This is what Jesus taught His disciples, which is why His disciples taught these things.
12 Those by the wayside are the ones who hear; then the devil comes and takes away the word out of their hearts, lest they should believe and be saved.13 But the ones on the rock are those who, when they hear, receive the word with joy; and these have no root, who believe for a while and in time of temptation fall away. Luke 8:12-13
Believe = Saved
Believe for a while = Saved for a while.
Those who endure to the end will be saved. Matthew 24:13
Still trying to create a fruit salad theology, I see. Mixing apples and oranges works well for a summer salad, but doesn't work at all for biblical theology.
The context for Matt 24 is the Tribulation only. Not applicable for all of humanity.
Second, you've never yet proven your theory that believing for a while means being saved for a while, and Luke 8:13 certainly does NOT teach that. Not even close.
However, the Bible does teach that the gifts of God are irrevocable. And that eternal life is a gift of God.
So, in order to prove your theory about loss of salvation, one MUST prove from Scripture by finding a verse that directly SAYS that eternal life can be lost, taken away, forfeited, revoked, etc.
And we all know that there is no such verse anywhere in Scripture.
So, Rom 11:29 is a "blanket statement" about the gifts of God. That verse teaches us that ALL of God's gifts are irrevocable. Precisely because Paul NEVER clarified by stating that ONLY SOME of them are irrevocable, or only many are. He SAID "the gifts of God". Because there is no other modifier with the gift of God, we can rest assured that he clearly meant ALL of them. Which includes the gift of eternal life.
Those who believe for a while are saved for a while.
This is totally unproven and only a theory. There are no verses to support such a notion.
Those who depart from Him in unbelief, are no longer partakers of Christ.
This is true, but your understanding of what it means to be a partaker of Christ means.
He who has the Son has life; he who does not have the Son of God does not have life. 1 John 5:12
When this verse is considered with Jesus' own words in John 10:28, I find it very hard to understand how one can even consider that salvation can be lost.
"and I give eternal life to them, and they will never perish; and no one will snatch them out of My hand."
It is Jesus that holds the believer. Which is WHY eternal life is IRREVOCABLE.
Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
1 John 2:23
Sure. No unbeliever either has eternal life or has salvation. No mystery there.
