Mathew 11:20-22
20Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear;
21for if God did not spare the natural branches, He will not spare you, either.
22Behold then the kindness and severity of God; to those who fell, severity, but to you, God’s kindness, if you continue in His kindness; otherwise you also will be cut off.
You quote the above from Matthew.
Here is the verses
Matthew 11:20-22
20 Then He began to rebuke the cities in which most of His mighty works had been done, because they did not repent: 21 “Woe to you, Chorazin! Woe to you, Bethsaida! For if the mighty works which were done in you had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes. 22 But I say to you, it will be more tolerable for Tyre and Sidon in the day of judgment than for you.
Slight difference
Anyway I knew what you are trying to convey
Romans 11:20-22
20 Well said. Because of unbelief they were broken off, and you stand by faith. Do not be haughty, but fear. 21 For if God did not spare the natural branches, He may not spare you either. 22 Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off.
The question I want to ask you is that do you think these verses negate eternal security or as you may think OSAS.
My guess is that you do.
I don't think this is the case.
I think it's do with nations.
The Jews and gentiles.
V 11-36 is about Israel rejecting Jesus.
Romans 11:19-21
19 You will say then, “Branches were broken off that I might be grafted in.” 20 Well said. Because of unbelief they were broken off, and you stand by faith. Do not be haughty, but fear. 21 For if God did not spare the natural branches, He may not spare you either.
Who were the natural branches and why were they cut off?
Who were the branches that were grafted into the vine
Romans 11:18-20
18 do not boast against the branches. But if you do boast, remember that you do not support the root, but the root supports you.
19 You will say then, “Branches were broken off that I might be grafted in.” 20 Well said. Because of unbelief they were broken off, and you stand by faith. Do not be haughty, but fear.
The issue is that the gentiles were boasting that they were superior to the Jews just like the Jews felt towards the gentiles.
But we find
Romans 11:23
23 And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again.
We must remember that Paul bought the Gospel to the gentiles because the Jews rejected the Gospel.
So it's not about individuals losing salvation it's about Gods redemptive plan for his chosen people, both Israel and the Gentiles.
Romans 11:25-27
25 For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the fullness of the Gentiles has come in. 26 And so all Israel will be saved, as it is written:
