You can not relegate fruit passages to salvation. That is sanctification.. In john 15. the words literally say in the greek that he lifts up. (takes away is the incorrect interpretation)
Source for that?
Virtually every translation renders it cut off or taken away, which is what the context suggests also. He cuts off is αἴρει (airei). It is possible, agreed, for this word to be rendered as "lifted up", but the contest suggests otherwise.
How do you read the passage? Every branch in Christ that does not bear fruit, He lifts up? What does that mean?
as for the 4 examples. Only the last one was ever saved., that is why he bore fruit. because he was attached to the vine
That's not correct. Christ said clearly about the second:
"13But 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."
See how clearly He says, they believe for a while then fall away. Since faith justifies, it justified him too, when he believed. He was justified but not saved. You see, OSAS is not the Doctrine of Christ, it is a doctrine of man.
as for the first example. God saved Israel. and yet they turned and refused to forgive others.. Not everyone in Israel was saved.
Sorry, that's a total misreading of the passage. Jesus is clearly speaking about a particular unforgiving servant.
That particular servant was justified at first. The Jews who did not believe in Christ were never justified.
That particular servant, who was at first justified, later on fell from grace and became lost. Again, justified but not saved.
Also, whom did Israel refuse to forgive exactly? Israel's - i.e. the Pharisees' - sin was not unforgiveness but unbelief.
eternal life is eternal. not conditional.
Eternal Life is a Metaphor for the Holy Spirit. When you receive the Holy Spirit, you have Eternal Life in you.
But if you sin unto death, e.g. by apostasy, as it says in 1 Jn 5, 2 Pet 2, Heb 6, Heb 10, etc, you return from Life to Death.
God Bless.
