The Bible says that a Spirit led life will not fulfill the lusts of the flesh, for they have crucified the flesh with the affections and lusts, and show the ways of the Spirit and not the flesh.
And God will not allow them to be tempted above what they are able to handle, and will give them an escape from the temptation so they can bear, which a saint will not be tempted as hard as the world.

So there is no excuse.

Which the Lord knows them that are His having this seal, that everyone that names the name of Christ depart from iniquity.
And awake to righteousness, and sin not, but some do not have the knowledge of God.
And if a person does not continue in the goodness of God they will be cut off, and do not depart from the living God by the deceitfulness of sins.
But we are still in the flesh and have the capability to sin if we want to sin, but those with the Spirit will repent, and get rid of the sin and keep moving forward having the right attitude that they are not right with God if they hold unto sin, which God said it is our sins that separate us from Him.
Where people that do not have the Spirit will hold unto sin, and sin with whatever sin they enjoy, and believe they still have salvation.
Which we grow in Christ, which when we first were saved we might of enjoyed sin for a while even though we toned it down until we gave it up, and then we might sin if we want but we get rid of it, where some did not give up the sin.

But we are not sinless, nor can we be sinless while in the flesh, although we can abstain from sin.
For in the flesh dwells no good thing, and we are tempted, and as long as we are tempted then we will not be sinless because of that battle between the Spirit and flesh, and we have the capability to sin if we want, and the flesh does want to sin.
For Paul said that when he does good, evil is still present with him, for there is no good thing that dwells in the flesh, so with the mind he serves Christ, but with the flesh he serves sin, not that he is sinning but there is no good thing that dwells in the flesh, and it is a part of him.
For a sinless life does not have a battle in them between good and evil, nor does it have the ability to sin, for all they see is good and no evil, and they are not tempted to sin, for the flesh is still trying to control a saint that is in the world.
Jesus was the only one who is sinless, and even though He was tempted there was no way He could sin for He was always led of the Spirit for the man Christ Jesus is the personal human body of God, and the express image of God, and Jesus always did good and could not do evil, so He is the only human that could be sinless on earth.
Jesus said that John the Baptist was the greatest person born of women for John had the Spirit from the womb, not to save him but to give him power to live a life that was right before God to prepare the way for Jesus, but the person who is the least in the kingdom of God is greater than John the Baptist.
For we are only sinless when we put off the flesh, for then there is no battle between good and evil, and the saints do not have the capability to sin, and all they see is good and not evil, for the choice is gone, and all sin resides in the flesh that is gone.
If we are led by the Spirit we can abstain from sin, and many people that have received the Spirit have sinned, but they get rid of it and keep moving forward, but the main thing is they have the right attitude that they cannot be right with God if they have sin in their life, so they get rid of it, and the Spirit convicts them to get rid of it.
And all sin can be forgiven even if you live in sin for a year, which some may take that chance, but it can still be forgiven.
Which the big thing is to have the right attitude that you cannot hold unto sin and be right with God, and the Spirit will not lead a person that does not hate sin, and does not want sin, for then they want to be led of the flesh.
