So I backslide, walkout or step away and go back to the things I once did while unsaved I am still saved?
That is the problem with Grace taken to the extreme. You walk away and die in your sins you will not enter the kingdom of God.
Gal 5:19-21
Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
