That in incorrect. The Bible makes it crystal clear that our good works do prove that we are saved. As James says, faith without works in dead.
JAMES 2: FAITH WITHOUT WORKS IS DEAD
14 What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him?
15 If a brother or sister be naked, and destitute of daily food,
16 And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit?
17 Even so faith, if it hath not works, is dead, being alone.
18 Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.
And what exactly is repentance other than genuinely TURNING FROM sins and idols and TURNING TO God and Christ for forgiveness and salvation. Indeed, the Lord Jesus Christ made it crystal clear that repentance is for the remission of sins: And [Christ] said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. (Luke 24:46,47)
Christians need to be extremely careful that in their zeal to maintain salvation is by grace through faith, they do not neglect the proclamation of two things: (1) the necessity of repentance before salvation and (2) the necessity of good works after salvation. In addition to this, the necessity of Christian baptism is a commandment.
There has been far too much Easy Believism, and it is time that Christians get back to Gospel Truth.
1 john 3:5 And ye know that he was manifested to take away our sins; and in him is no sin. [ This tells us that we are not to commit sin,]
3:6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him. [This tells us if we choose to sin, we are choosing to be lost], [neither do we know him if we will choose to sin. [ to sin is denying the faith.]
3:7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
[ this is telling us not to let no one deceive us, that we can commit sin and still be saved].
[ And that being righteous is obeying God, like YESUAH said he OBEYED ]
3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
[This is telling us if we will commit sin when we know that it is sin, that we belong to Satan
and not one of GOD's Saved ] [And that YESUAH came to show us, that through faith we can
overcome committing SIN] [ and he came to destroy the works of the devil that we are doing]
3:9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
[this is telling us that if we are committing sin, that we have not came to the point of being saved]
HEBREWS 10:26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
10:27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
10:28 He that despised Moses' law died without mercy under two or three witnesses:
