Today's American churches are absolutely filled with people
who are involved with deliberate pre-planned sin!
And you're telling me they are going to heaven?
Or, they never initially received the Holy Spirit?
Ridiculous.
They are believers who have departed from the faith
... and have fallen from grace!
There is no one in heaven with unrepented-of sin.
Sorry but scripture says believers have the indwelling Holy Spirit.
Matthew Henry calls such you are trying to describe as 'empty professors'
And he also says they are not saved, they were never repenting and believing in Christ,
they went through the rituals, but their deeds showed they did not have a true conversion, they were not born again.
Preplanned sin is presumptuous sin. You know unbelievers add sin to sin, they continue in sin without stopping.
Obviously they do not have the Holy Spirit or they would be restrained by God. The Holy Spirit leads His people into truth and leads in the way they are to walk. In fact, the discipline of the Lord is mentioned, if you belong to the Lord, then you will be disciplined by Him, otherwise your not belonging to Him.
I get the sense you have this big disconnect in your life, placing all the disciplining on what the Christian is to do, and leaving God completely out of the loop.
However it tells us 'SONS' is how God deals with us and not as illegitimate children of the world who have no FATHER in heaven that disciplines them. People of the world are NOT SONS and are not disciplined by God, they are not God's children.
But those who are God's children, God corrects and rebukes so they they are conformed to the image of His Son. And believe me, God' s able to subdue and make all things conform to the purpose of His will. And His will is none of those He gives to Christ as believers will be lost and perish. And His will is done, as it states in Eph 1.
Heb 12
5 And you have forgotten the exhortation which speaks to you as to sons:
“My son, do not despise the chastening of the Lord,
Nor be discouraged when you are rebuked by Him;
6 For whom the Lord loves He chastens,
And scourges every son whom He receives.”
7 If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten? 8 But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons. 9 Furthermore, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live? 10 For they indeed for a few days chastened usas seemed best to them, but He for our profit, that we may be partakers of His holiness.11 Now no chastening seems to be joyful for the present, but painful; nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been trained by it.
