17But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree, 18do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you. 19You will say then, “Branches were broken off so that I might be grafted in.” 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. 23And they also, if they do not continue in their unbelief, will be grafted in, for God is able to graft them in again.
If you try anything other than God to gain Heaven you will be cut off. The other verses you cite, if read in context, will indicate the same.
It is about faith in Him. Not works.
You just ignore the Word in the Bible:
Eagleone’s comment/spin; “It is about faith in Him. Not works.”
Yes we all need to have faith in Jesus and His Church, but our actions (works) need to reflect that faith. We are to love God and our neighbor.
Hebrews 11
We must consider how to rouse one another to love and good works. 25We should not stay away from our assembly,* as is the custom of some, but encourage one another, and this all the more as you see the day drawing near.r
26* s If we sin deliberately after receiving knowledge of the truth, there no longer remains sacrifice for sins 27but a fearful prospect of judgment and a flaming fire that is going to consume the adversaries.t 28Anyone who rejects the law of Moses* is put to death without pity on the testimony of two or three witnesses.u 29Do you not think that a much worse punishment is due the one who has contempt for the Son of God, considers unclean the covenant-blood by which he was consecrated, and insults the spirit of grace?v 30
Concerning Romans, there is another passage that the non productive branches of the vine will be pruned. John 15
I am going to repeat the reference to the Real Presence - HIS BODY AND HIS BLOOD: “the one who has contempt for the Son of God, considers unclean the covenant-blood by which he was consecrated, and insults the spirit of grace?”
