"Presumption is the crime of idolatry." 1 Sam. 15 this made me think of the "once saved always saved" frightening 'doctrine.'
Forgive me Lord, when I have presumed upon/cheapened your grace. May my sin ever be before me, as King David prayed and all of the Saints now in heaven. I realize how easily I can be led astray. "Work out your salvation with fear & trembling." That's a verse seldom quoted by "bible believing Christians." They don't like it. One friend of mine had a real problem with St. James (as did Luther) and didn't like to read that book, especially verse 2:24. Hmm. To presume we are 'saved' from one "sinner's prayer" uttered over 30 years ago & that we're never in any danger of losing our salvation, is nothing BUT presumption. No Saint ever presumed such a thing. Neither can I. Lord have mercy.
