Of course it can be true that: 1) sinners must believe on the Lord Jesus Christ in order to be saved, whilst at the same time, 2) God's enabling is required for a sinner to believe on the Saviour.
Your last sentence, "But your religion says salvation is unconditional which is clearly an errant view." shows me that you are still misunderstanding what I believe. You seem to suggest that I believe that I am saved regardless of whether or not I believe on the Lord Jesus Christ. Let me assure you that any sinner, me included, must believe on the Lord Jesus Christ to be saved.
Think about what you just wrote David:
"Of course it can be true that:
1) sinners must believe on the Lord Jesus Christ in order to be saved, whilst at the same time,
2) God's enabling is required for a sinner to believe on the Saviour."
So if God does not enable a person to believe then it is impossible for them to believe, correct? But what is the outcome of that view? Those that reject God have the best excuse going when asked by God why they should not be cast into hell? "God did not enable them to believe" therefore if God is just, and He is, then He cannot cast them into hell as they did not have the ability to trust in His son.
When you remove responsibility from the person then you also remove the consequence.
But when we look at scripture we see that God desires all to come to Him so He either gave all men the ability to trust in Him or He is being disingenuous knowing full well that all men cannot do as He desires as He has not given them the ability to do so.
What you believe to be biblical is not the question, it is what is actually biblical.
Look at your DoG/TULIP and what does it show us?
Only those that are included in the Unconditional Election that will partake of the Limited Atonement will then be drawn to God by His Irresistible Grace.
Your religion also claims that you were in Christ before creation.
If, according to Calvinism, you are not part of this select group then you are doomed form the start.
When one is in Christ they are saved. Therefore if you were in Christ B4 creation you were saved B4 you believed.
Those of the C/R view have even gone so far as to state that one is saved before they believe.
"A man is not saved because he believes in Christ, he believes in Christ because he is saved."
Loraine Boettner The Reformed Doctrine of Predestination, Page 75
As a bible believer I can fully agree with what Paul said to the jailer without qualification. Those that hold to the C/R philosophy cannot do that.
As long as you hold to the C/R philosophy then you are in disagreement with the word of God.
