Unfortunately (or fortunately) all of TULIP stands or falls together. Neither T nor P are found in Scripture, but are the inventions of men.
Let's take P. Scripture says that the saints are "kept by the power of God" so the P should be "power of God" not "perseverance of the saints".
As for T, I have shown elsewhere how utterly false it is when compared to what the Bible reveals. All humans beings are not continually and totally evil, and totally unable to respond to the Gospel under the power of the Gospel and the power of the Holy Spirit. And all human beings have a conscience, which does cause many to do right, even though they are not saved. God tells us that they are regulated by "the Law" which is within their conscience.
Christians need to see what is actually stated in the Calvinist confessions of faith, not what Calvinists "think" is stated.
