We can each post one Scripture after another from now until the Lord comes again without resolving anything.
Read the letter to the Laodecian's and notice the word "erase". Is the Lord making an empty threat? I can also point to Hebrews 6:4-8 where we are told that it is impossible to renew one who falls away. Eternal security or OSAS is not taught in Scripture and is a comparatively new Christian concept. Calvin was the first to advance this doctrine; a doctrine that is not accepted by the vast majority of Christians.
