Salvation depends on one thing, believing on the Lord Jesus Christ.(Acts 16:30-31)
Sounds like You Can lose it.
REVELATION 3:15"I know your Deeds, that you are neither cold nor hot. I wish you were either one or the other! 16So, because you are lukewarmneither hot nor coldI am about to SPIT you out of my mouth."
Gee I think it looks like they have the HOLY SPIRIT
But still be be Spit out.
