Hi Stephen63,
I don't know much about these people your talking about above, but I know one thing God's Word tells us if the "Gospel" you believe in has no power to change your life it is not the Gospel of Christ. It is spoken about here....
Rom 6:22
But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.
2Co 7:1
Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
Eph 4:24
And that ye put on the new man, which after God is created in righteousness and true8 holiness.
1Th 4:7
For God hath not called us unto uncleanness, but unto holiness.
Heb 12:10
For they verily for a few days chastened us after2 their own pleasure; but he for our profit, that we might be partakers of his holiness.
1Pe 1:16
Because it is written, Be ye holy; for I am holy.
Heb 12:14
Follow peace with all men, and holiness, without which no man shall see the Lord:
2Ti 3:5
(Those that have the false Gospel are those that are) Having a form of godliness, but denying the power thereof: from such turn away.
God bless
