When believers choose to live sinful lifestyles (i.e. have an attitude of I do not care whether I sin or not, since I love sin and it is my lifestyle), does that mean they would reject eternal security if their intent is to live a sinful lifestyle? Or does it reveal that they are not truly saved?
I’ve never met a truly born again believer who says, “I do not care whether whether I sin or not, since I love sin and it is my lifestyle.” Born again believers have the Holy Spirit as a guide and counselor, and while we do sin, the conviction of the Holy Spirit makes our sins embarrassing and disappointing to us, and bring us in shame to the cross for forgiveness. I don’t make judgments about the spiritual state of others, but if I did I would wonder whether a person who doesn’t care about sin is truly saved.
