——>Accepting Jesus Christ as your lord and savior must be coupled with repentance and godly sorrow.
Nope, not according to FR biblical “experts”. OSAS/OJAJ means just that. Still going to heaven, no matter what. All you have to do is believe. Conduct is optional. God’s law is only for the unsaved.
IF they continue in their chosen lifestyle it's a very good indication they haven't repented and therefore are not saved.
You just described the person Jesus talked about in Matthew 7:21: “Not everyone who calls out to me, ‘Lord! Lord!’ will enter the Kingdom of Heaven. Only those who actually do the will of my Father in heaven will enter." Lots of people say the sinner's prayer and think they are saved. Many are not. If all it took was a simple, insincere prayer then it would be the wide path that leads to the Kingdom, not the narrow one. And there are others who are truly saved but fall in some way later on. Ain't none of us perfect, after all. The indwelt Holy Spirit will convict that person of the need to repent - like David when confronted about his sin with Bathsheba. With sexual sins in particular, one can ignore the Spirit and keep sinning, but the cognitive dissonance involved would be terrible to bear. That person, if truly saved, still gets to Heaven, but will have a horribly unhappy life. Someone who hedonistically keeps sinning without a care in the world was never saved in the first place.
