She’s accepted Jesus as her savior, yes? He says of those who are His, “I give them eternal life, and they shall never perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all; no one can snatch them out of my Father’s hand.” (John 10:28–29) So, you either believe this or you make God out a liar.
“So, you either believe this or you make God out a liar.”
You don’t see the problem do you? If you actually think about it someone can believe in Jesus but “snatch them[selves] out of” Jesus’ hand. You are creating a false dichotomy. It is not:”either [you] believe this or you make God out [to be] a liar.” I believe everything in that verse. Every word of it. I also believe that we can lose our salvation by our own actions separating ourselves from God.
