Hebrews chapter 12
6-whom the Lord loveth he chasteneth and scourgeth every son whom he recieves.
7-if ye endure chastening God deals with you as sons,for what son is he whom the father chasteneth not?
8-BUT if ye be without chastisement,whereof ALL(Saints)are partakers,then are ye BASTARDS,and not sons
these verses state that the child of God does recieve chastening from God.
if a person remains in Sin without any chastening and is never bothered about their sin and also may enjoy their sin,they are not saved and are Bastards instead of Sons as the scripture just stated.
1st John chapter 3:
8-he that committeth sin is of the DEVIL
9-whosoever is born of God doth not commit sin,his seed remaineth in him,and he cannot sin,because he is born of God
10-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
the word commit or committeth does not mean a one time sin.it is talking about a ongoing lifestyle of sinning.
so those who are in sin for a time period and does not recieve chastening from God is evidence that they are NOT saved and not of God.
you can even be in church everytime the door opens,and can take part with all that goes on in the church,but can be in a lifestyle of SIN.
there are many diff types of sin you can be in,question is are you enjoying your life style of the sin?
