The Holy Spirit guides to do good,but the decision is up to us whether to listen or not,which sometimes we do not listen,and sin,but good thing sin can be forgiven,for if not who could make it.
Even the great Peter was not walking uprightly according to the Gospel of truth,and Paul told him to stop what he was doing,and walk uprightly,which Peter is a good example of one who messes up quite frequently,but still finds favor with God,because of His determination.
But even without the Spirit,we still know right from wrong,and make a decision,mainly in how we deal with other people,whether it is love or not,which is the biggest factor that can cause us to stumble,for the love of people is the fulfilling of the law.
When we are led of the Spirit we already know what is right,and what is wrong,according to the will of God,without the Spirit convicting us,but the Spirit will guide us to do good,which when we are tempted God will not put upon us more than we are able to bear,and will with the temptation give us an escape from it,so we can endure it and not sin.
Mainly the Spirit guides us to show His characteristics,love,joy,peace,longsuffering,gentleness,goodness,faith,meekness,and temperance,and with those traits we do not offend people,and love them correctly,and show them the kingdom,and lessens the intensity of the temptation upon the saint so they can endure the temptation,and beat it easier,but we know right from wrong even without the Spirit,or else the world would not be judged.
But that is to saints that are actually not wanting sin the temptation is lessened,but to those who hold unto sin it does not matter,for they will sin even if the temptation is not even tugging on them.It is a habit to them,and they are not trying to beat it.
It is not sin that can cause us to lose our relationship with God,for sin can be forgiven,and we move on,but it is holding unto sin and thinking we are right with God that is the problem,but if we hold unto sin even for a year it can be forgiven,but some people that hold unto sin and think they are right with God might not get rid of it ever,and that is why they are learning,but never able to come to the knowledge of the truth.
We should have the attiude sin does affect our relationship with God,so then when we sin,or hold unto sin,we will deal with it properly,and eventually give it up,but with that attitude most likely we will hate sin,and not want sin,although we can be like Peter and might mess up,but Peter always corrected himself,and is saved,for his name,along with the other apostles,are written in the New Jerusalem.
Does the Holy Spirit convict us before we sin,which we know right from wrong without the Spirit,but goodness is one of the fruits of the Spirit that a saint will display,so without the Spirit we might not feel so guilty,and bad,concerning a sin,but with the Spirit we will feel more guilty,and bad,if we entertain a sinful thought,and want to do it,for the hate that God has for sin will be in us.
For we could steal in the world,and not feel so bad about it,or if we felt a little bad,could shrug it off easily,and steal away,but with the Spirit the hate that God has towards sin will be in us,and it will appear to be worse,and not so easy to shrug off,as when we were in the world.
Rom 7:12 Wherefore the law is holy, and the commandment holy, and just, and good.
Rom 7:13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
The law was given to point out sin is bad,and the Spirit will point out that it is worse than we thought while in the flesh,by making us hate sin,and know how bad it is,as the Father does.
If you have the Spirit you should have the attitude towards sin as the Father does,for if led of the Spirit you display the ways of the Spirit,and the Spirit hates sin.The Spirit will cause you to look at sin as disgusting,and nasty,and uncomfortable to a believer to engage in.
That is what is strange about people that hold unto sin while claiming Jesus as Lord,and say they are led of the Spirit,but do not look at sin as disgusting,for how can they do it if they are led of the Spirit.
