your salvation can’t be taken away by anyone, but YOU can walk away from it and reject it. we still have free will. the atheist guy on this thread did exactly that.
That is presuming the guy was correct about being saved and was actually saved in the first place.
So you say that a person can thwart Gods plan or reject it regardless of what He says?
John 10: 25 Jesus answered, I did tell you, but you do not believe. The works I do in my Fathers name testify about me, 26 but you do not believe because you are not my sheep. 27 My sheep listen to my voice; I know them, and they follow me. 28 I give them eternal life, and they shall never perish; no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all[c]; no one can snatch them out of my Fathers hand. 30 I and the Father are one.
