Behold, I, Paul, tell you that if you receive circumcision, Christ will profit you nothing. Yes, I testify again to every man who receives circumcision that he is a debtor to do the whole law. You are alienated from Christ, you who desire to be justified by the law. You have fallen away from grace.(Galatians 5:2-4 WEBPB) - Here Paul is warning those who began again to keep the Law of Moses that they've become alienated from Christ and fallen from grace.
True; by their unbelief they were broken off, and you stand by your faith. Don’t be conceited, but fear; for if God didn’t spare the natural branches, neither will he spare you. See then the goodness and severity of God. Towards those who fell, severity; but towards you, goodness, if you continue in his goodness; otherwise you also will be cut off.(Romans 11:20-22 WEBPB)
I therefore run like that, not aimlessly. I fight like that, not beating the air, but I beat my body and bring it into submission, lest by any means, after I have preached to others, I myself should be disqualified.(1 Corinthians 9:26-27 WEBPB)
Now I would not have you ignorant, brothers, that our fathers were all under the cloud, and all passed through the sea; and were all baptised into Moses in the cloud and in the sea; and all ate the same spiritual food; and all drank the same spiritual drink. For they drank of a spiritual rock that followed them, and the rock was Christ. However with most of them, God was not well pleased, for they were overthrown in the wilderness. Now these things were our examples, to the intent we should not lust after evil things as they also lusted. Don’t be idolaters, as some of them were. As it is written, “The people sat down to eat and drink, and rose up to play.” Let’s not commit sexual immorality, as some of them committed, and in one day twenty-three thousand fell. Let’s not test Christ, as some of them tested, and perished by the serpents. Don’t grumble, as some of them also grumbled, and perished by the destroyer. Now all these things happened to them by way of example, and they were written for our admonition, on whom the ends of the ages have come. Therefore let him who thinks he stands be careful that he doesn’t fall. No temptation has taken you except what is common to man. God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it. Therefore, my beloved, flee from idolatry.(1 Corinthians 10:1-14 WEBPB)
You, being in past times alienated and enemies in your mind in your evil deeds, yet now he has reconciled in the body of his flesh through death, to present you holy and without defect and blameless before him, if it is so that you continue in the faith, grounded and steadfast, and not moved away from the hope of the Good News which you heard, which was proclaimed in all creation under heaven, of which I, Paul, was made a servant.(Colossians 1:21-23 WEBPB)
But the Spirit says expressly that in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons, through the hypocrisy of men who speak lies, branded in their own conscience as with a hot iron, forbidding marriage and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth. For every creature of God is good, and nothing is to be rejected if it is received with thanksgiving. For it is sanctified through the word of God and prayer. If you instruct the brothers of these things, you will be a good servant of Christ Jesus, nourished in the words of the faith and of the good doctrine which you have followed. But refuse profane and old wives’ fables. Exercise yourself towards godliness. For bodily exercise has some value, but godliness has value in all things, having the promise of the life which is now and of that which is to come. This saying is faithful and worthy of all acceptance. For to this end we both labour and suffer reproach, because we have set our trust in the living God, who is the Saviour of all men, especially of those who believe. Command and teach these things. (1 Timothy 4:1-11 WEBPB)
If we endure, we will also reign with him. If we deny him, he also will deny us.(2 Timothy 2:12 WEBPB)
The books of Paul are not the only books that apply to Christians, however. That is just another one of the false doctrines that you purport. As it is written, "But evil men and impostors will grow worse and worse, deceiving and being deceived" (2 Timothy 3:13). Here's some more examples from Paul and the other writers who, I remind you, all wrote these scriptures under the influence of God's Holy Spirit:
