I see TULIP as trying to go beyond scripture, which invalidates it. Jesus never said "ALL were lost," particularly in relation to the lineage of Adam in the bible: e.g. Noah, Abraham etc. He never said "MY sheep cannot hear or respond to my voice." He never said "Faith is unconditional" in that he actually said "Faith requires work." And he never suggested that a man being depraved, apart from God, was other than self-evident: the question is therefore: is it necessary for EVERY man to become "apart from God?" The biblical answer is NO. Not every man who ever lived fell into the state of being "apart from God." See especially John the Baptist who had the Holy Spirit from birth. So I find TULIP to be using obscure terminology that doesn't resonate with biblical language (e.g. unconditional election is NOT in the bible).
I also find the exegesis of certain passages in John by adherents of TULIP to be objectively faulty, in that they appear not to grasp that Christ is distinguishing apostates from non-apostates. Not every man falls into the "apostate" category, even if most fall into the "lost" category. "Lost" doesn't mean "apostate". Paul also distinguishes faithlessness from apostasy. The distinction is vital. Apostates, whether from Moses or from Christ, are difficult to reach with the word of God, as they cannot hear it, but as always it's up to God.
Only the perservance of the saints I find to be a plausible thesis as stated, but I don't find it articulated quite as Christ articulated it, for he stressed the providential protection of God keeping his children safe from satan, whereas Calvinism limits the point to those whom God has chosen before the foundation of the world, which is true, in that such are all destined to become God's adopted children, at some point, but which isn't quite to the point of what Christ was talking about, in terms of the dynamic of God's relationship with his adopted children, but which still allows for them (or at least those who pass for God's children) to apostatize in opposition to the will of God (e.g. Israel in the Old Testament). IOW, Christ is stressing that if you are God's child, God will keep you safe, but if in the end God lets you go, you cannot blame it on God, but only on your own decision to apostatize despite God's protection. This ties in with viewing Christians as having very different degrees of spiritual maturity: some are blown about by the wind, some have deep roots etc.
