No, that’s what the Catholic faith believes - that you must preservere to the end in good works. The Bible says that “if thou shalt confess with thy mouth, and believe in thy heart, thou shalt be saved…”
Mat 7:21 Not every one that saith to me, Lord, Lord, shall enter into the kingdom of heaven: but he that doth the will of my Father who is in heaven, he shall enter into the kingdom of heaven. [not everyone who calls upon the name of the Lord will enter into heaven?!?!]
Luk 6:46 And why call you me, Lord, Lord; and do not the things which I say?
Mat 10:22 And you shall be hated by all men for my name’s sake: but he that shall persevere unto the end, he shall be saved.
Mat 24:13 But he that shall persevere to the end, he shall be saved.
Mar 13:13 And you shall be hated by all men for my name’s sake. But he that shall endure unto the end, he shall be saved.
Source: the same Bible that says if you confess Christ with your mouth [which is a work by your definition], then you shall be saved. Obviously if both statements are true, then it’s a both-and, not an either-or. You must both confess Christ
and endure to the end to be saved. All of Scripture is true. There is a danger inherent when one begins with texts that support the doctrines he already believes or already finds most convincing to the exclusion of those that seem to contradict. We must be careful to realize the teachings we received that tell us what the Scriptures mean for we then interpret them in light of those already accepted beliefs. The early Church fathers received a living Tradition from the apostles, and this Christian faith was spread all over the world. This is the Tradition that helps us understand the most accurate way to understand Scripture.
Here are some more verses that you will hopefully find helpful as well:
Heb 12:14 Strive for peace with all men, and for the holiness without which no one will see the Lord.
2Th 1:5 This is evidence of the righteous judgment of God, that you may be made worthy of the kingdom of God, for which you are suffering
2Th 2:13 (2:12) But we ought to give thanks to God always for you, brethren, beloved of God, for that God hath chosen you firstfruits unto salvation, in sanctification of the spirit
and faith of the truth:
Rom 13:11 And that, knowing the season, that it is now the hour for us to rise from sleep. For now our salvation is nearer than when we believed.
Philippians 3:11-14 If by any means I may attain to the resurrection which is from the dead. Not as though I had already attained,* or were already perfect*: but I follow after, if I may by any means apprehend, wherein I am also apprehended by Christ Jesus. Brethren, I do not count myself to have apprehended. But one thing I do: Forgetting the things that are behind and stretching forth myself to those that are before, I press towards the mark, to the prize of the supernal vocation of God in Christ Jesus.
1 John 2:3-5 And by this we know that we have known him, if we keep his commandments. He who saith that he knoweth him and keepeth not his commandments is a liar: and the truth is not in him. But he that keepeth his word, in him in very deed the charity of God is
perfected. And by this we know that we are in him.
[If you are breaking the commandments of God, then you are not in Christ. You are a withered branch that God will remove unless you repent and be rejoined to the Vine. If God is in control of your will as you say, then you would never sin, and if you sin, then you were never really converted in the first place then were you? The truth is that one is initially justified but must endure to the end in that faith, hope, and charity to be saved. If he should fall into serious sin, his former righteousness he received from Christ will not be remembered in the eyes of God but the wrath of God will abide upon him unless he repent.]
1Ti 4:1 Now the Spirit manifestly saith that in the last times some shall
depart from the faith, giving heed to spirits of error and doctrines of devils.
Hebrews 10:26-29 For if we sin wilfully after having the knowledge of the truth, there is now left no sacrifice for sins: But a certain dreadful expectation of judgment, and the rage of a fire which shall consume the adversaries. A man making void the law of Moses dieth without any mercy under two or three witnesses: How much more, do you think he deserveth worse punishments, who hath trodden under foot the Son of God and hath esteemed the blood of the testament unclean,
by which he was sanctified, and hath offered an affront to the Spirit of grace?
1 John 5:16-17 “… There is a sin which is mortal … There is a sin which is not mortal.”
