I think it was pretty obvious from her post that they believed the gospel of Christ. All who are baptized into Christ are in Christ. They are circumcised in the heart and become members of the new covenant. That is by definition being saved.
I met someone exactly like she described. He was formerly a devoted Christian who turned his back completely on Christ and disavowed him.
How is it that you can come to faith in Christ, but not fall out of faith in Christ?
How many marriages start saying we will divorce, it is just a question of time? No they start we will live together like this forever...
What is also odd is if you suggest you observe what faith is, its beauty and its fragility, you are now an unbeliever.
Many sincere Christians have ended up atheists, and sincere atheists Christians.
I have a deep respect for some of the atheists sincerity on how they define truth.
One thing staggared me, was a relationship I had with a brother. I shared for years about the glorious nature of Christs love for us. One day his son a teenage 19, stood up to him, and swore. My friend lost it and smacked the boy round the head.
He had grown up with automatic respect for your dad culture, and here was his son throwing this over.
It went so deep in this man, he said he would never forgive his son even if he went to hell. After about a year, finally the Lord broke through again with humbleness and love, and my friend repented and came back to the Lord.
Now I share this because people follow Jesus for many different reasons and have many issues unresolved in who they are, which may take them away. The seed works through us, and changes us, but only on the outside can others see.
Those who talk of instant anything have little experience of real life and real people. It is always a walk.
So I always say, I a sinner am redeemed by Christ crucified, I cannot boast in anything say His work in me.
His work in me is not down to a teacher, or theology but the work of the Holy Spirit through His word. That has always been enough for me.
