No it doesn't. Christians are saved from Hell no matter how many or what kinds of sins that they commit. It doesn't excuse them, but Jesus still paid the penalty for them.
For Christians, God does not impute sin to their account, as in will not hold it against them regarding having eternal life, he passes over the sins previously committed.
However we are not to commit sins willfully as that ensures judgement against us. But still not to eternal death.
All of us sin, Christians still sin. If they deny their sin, then the truth is not in them.
We sin in our bodies, and we find ourselves as flesh and blood creatures for now,
Romans 8:9-11
New King James Version
9 But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His. 10 And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. 11 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
But we are more then physical creatures when born again, we have a new spirit inside of us, joined to God as one spirit with Him, and that part of us is created in righteousness and holiness and that part can not sin
About our spirit in Christ this,

Judgement leading to physically dying due to a christian's particular sinning behavior, such as willful, unrepent sins
1 John 5:16
If anyone sees his brother sinning a sin
which does not
lead to death, he will ask, and He will give him life for those who commit sin not
leading to death. There is sin
leading to death. I do not say that he should pray about that.
