You call them "worthy" as though it was by their works that they had faith in Jesus, but the Scriptures says otherwise. To repeat, Romans 11:5-6 (WEB):
(5) Even so then at this present time also there is a remnant according to the election of grace.
(6) And if by grace, then it is no longer of works; otherwise grace is no longer grace. ...
and Ephesians 2:8 (WEB):
(8) for by grace you have been saved through faith, and that not of yourselves; it is the gift of God,
All Christians are only Christians because God made them so. Your faith was given to you by God, however much you think it was your own decision. All others, who you refer to as carnal dupes, are only so because God made them so - it is all God's work. So you should have a more gentle, loving, compassionate attitude towards them. As Jesus said, Matthew 11:29 (WEB):
(29) ... learn from me, for I am gentle and humble in heart; ...
and Paul said, Philippians 2:1-4 (WEB):
(1) If therefore there is any exhortation in Christ, if any consolation of love, if any fellowship of the Spirit, if any tender mercies and compassion,
(2) make my joy full, by being like-minded, having the same love, being of one accord, of one mind;
(3) doing nothing through rivalry or through conceit, but in humility, each counting others better than himself;
(4) each of you not just looking to his own things, but each of you also to the things of others.
John 6:44-45 (WEB):
(44) No one can come to me unless the Father who sent me draws him, and I will raise him up in the last day.
(45) It is written in the prophets, ‘They will all be taught by God.’ Therefore everyone who hears from the Father, and has learned, comes to me.
I have read all of Romans 11. Perhaps you should read all of Romans 3 (WEB):
(1) Then what advantage does the Jew have? Or what is the profit of circumcision?
(2) Much in every way! Because first of all, they were entrusted with the revelations of God.
(3) For what if some were without faith? Will their lack of faith nullify the faithfulness of God?
(4) May it never be! Yes, let God be found true, but every man a liar. As it is written, “That you might be justified in your words, and might prevail when you come into judgment.”
(5) But if our unrighteousness commends the righteousness of God, what will we say? Is God unrighteous who inflicts wrath? I speak like men do.
(6) May it never be! For then how will God judge the world?
(7) For if the truth of God through my lie abounded to his glory, why am I also still judged as a sinner?
(8) Why not (as we are slanderously reported, and as some affirm that we say), “Let’s do evil, that good may come?” Those who say so are justly condemned.
(9) What then? Are we better than they? No, in no way. For we previously warned both Jews and Greeks, that they are all under sin.
(10) As it is written, “There is no one righteous; no, not one.
(11) There is no one who understands. There is no one who seeks after God.
(12) They have all turned away. They have together become unprofitable. There is no one who does good, no, not so much as one.”
(13) “Their throat is an open tomb. With their tongues they have used deceit.”“The poison of vipers is under their lips;”
(14) “whose mouth is full of cursing and bitterness.”
(15) “Their feet are swift to shed blood.
(16) Destruction and misery are in their ways.
(17) The way of peace, they haven’t known.”
(18) “There is no fear of God before their eyes.”
(19) Now we know that whatever things the law says, it speaks to those who are under the law, that every mouth may be closed, and all the world may be brought under the judgment of God.
(20) Because by the works of the law, no flesh will be justified in his sight. For through the law comes the knowledge of sin.
(21) But now apart from the law, a righteousness of God has been revealed, being testified by the law and the prophets;
(22) even the righteousness of God through faith in Jesus Christ to all and on all those who believe. For there is no distinction,
(23) for all have sinned, and fall short of the glory of God;
(24) being justified freely by his grace through the redemption that is in Christ Jesus;
(25) whom God sent to be an atoning sacrifice, through faith in his blood, for a demonstration of his righteousness through the passing over of prior sins, in God’s forbearance;
(26) to demonstrate his righteousness at this present time; that he might himself be just, and the justifier of him who has faith in Jesus.
(27) Where then is the boasting? It is excluded. By what kind of law? Of works? No, but by a law of faith.
(28) We maintain therefore that a man is justified by faith apart from the works of the law.
(29) Or is God the God of Jews only? Isn’t he the God of Gentiles also? Yes, of Gentiles also,
(30) since indeed there is one God who will justify the circumcised by faith, and the uncircumcised through faith.
(31) Do we then nullify the law through faith? May it never be! No, we establish the law.
