So then -- "Sola scriptura" -- it is.
Romans 11
13 But I am speaking to you who are Gentiles. ...
20 Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; 21 for if God did not spare the natural branches, He will not spare you, either. 22 Behold 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. 23 And they also, if they do not continue in their unbelief, will be grafted in, for God is able to graft them in again
Romans 2
25 For indeed circumcision is of value if you practice the Law; but if you are a transgressor of the Law, your circumcision has become uncircumcision. 26 So if the uncircumcised man keeps the requirements of the Law, will not his uncircumcision be regarded as circumcision? 27 And he who is physically uncircumcised, if he keeps the Law, will he not judge you who though having the letter of the Law and circumcision are a transgressor of the Law? 28 For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh. 29 But he is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter; and his praise is not from men, but from God.
Matt 18 (Forgiveness revoked)
31 So when his fellow slaves saw what had happened, they were deeply grieved and came and reported to their lord all that had happened. 32 Then summoning him, his lord *said to him, ‘You wicked slave, I forgave you all that debt because you pleaded with me. 33 Should you not also have had mercy on your fellow slave, in the same way that I had mercy on you?’ 34 And his lord, moved with anger, handed him over to the torturers until he should repay all that was owed him. 35 My heavenly Father will also do the same to you, if each of you does not forgive his brother from your heart.”
1 Cor 9
26 Therefore I run in such a way, as not without aim; I box in such a way, as not beating the air; 27 but I discipline my body and make it my slave, so that, after I have preached the Gospel to others, I myself will not be disqualified from it.
1 Cor 6
7 Actually, then, it is already a defeat for you, that you have lawsuits with one another. Why not rather be wronged? Why not rather be defrauded? 8 On the contrary, you yourselves wrong and defraud. You do this even to your brethren.
9 Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor homosexuals, 10 nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God. 11 Such were some of you; but you were washed, but you were sanctified, but you were justified
Ezekiel 18 (forgiveness revoked)
24 “But when a righteous man turns away from his righteousness, commits iniquity and does according to all the abominations that a wicked man does, will he live? All his righteous deeds which he has done will not be remembered for his treachery which he has committed and his sin which he has committed; for them he will die. 25 Yet you say, ‘The way of the Lord is not right.’ Hear now, O house of Israel! Is My way not right? Is it not your ways that are not right? 26 When a righteous man turns away from his righteousness, commits iniquity and dies because of it, for his iniquity which he has committed he will die. 27 Again, when a wicked man turns away from his wickedness which he has committed and practices justice and righteousness, he will save his life.
