Not at all, you clearly do not have an understanding of how a Christian Goes to heaven. Repentance is an act on YOUR human level, and that is not what takes you to heaven. We are saved by grace THROUGH faith!
All humans are born in sin that is undeniable and because of that root sin we commit sins. Those sins are an abomination in the sight of a holy and righteous God and because all humans have broken God's holy law all are under a duty to repent of them.
Repentance and faith are both fruits of electing grace and indeed we are saved by grace through faith in Christ.
If I punched you in the face and said sorry and then punched you again then my applogy meant nothing for as James teaches faith without works is dead faith and will not save (not that faith is meritorious but rather instrumental).
Hence John teaches
1Jn 1:5-9 "This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness."
1Jn 2:3-5 "And hereby we do know that we know him, if we keep his commandments. He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him. But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him."
1Jn 2:29 "If ye know that he is righteous, ye know that every one that doeth righteousness is born of him."
1Jn 3:2-10 "Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. And every man that hath this hope in him purifieth himself, even as he is pure. Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. And ye know that he was manifested to take away our sins; and in him is no sin. Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him. Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous. 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. 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. In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother."
