My comment was to emphasize that there are “Christians” who have never accepted Christ as their savior; therefore “unsaved christians.” They never were saved to begin with.
Certainly once saved, always saved, can contribute in people who think they are saved and continue to live a life of sin. No different than a catholic attending every mass, every confession, saying every rosary. You must accept the gift given. All of the rest of it is our growth in Christianity, the pursuit to become more Christ-like.
And there are none more spiritually persecuted than those that accept the gift and are filled with the holy spirit. Spiritual warfare is deadly. But if the Christian is not persecuted by the Holy Spirit for sinful behavior, then you need to seriously question whether you have truly bended knee and accepted the gift.
But Christ states that you cannot be taken away from the Hand of God. It is a one way street.
Your growth (walk, works) after salvation helps you face adversity and withstand the temptations that will be lobbed toward you. And our reward will be in heaven, not here.
“But Christ states that you cannot be taken away from the Hand of God. It is a one way street.”
You cannot be taken away, but you can choose to jump out. I see no other explanation for the very explicit description in Hebrews 6:
“For it is impossible to renew to repentance those who were once enlightened,
who tasted the heavenly gift,
who shared in the Holy Spirit,
who tasted God’s good word and the powers of the coming age,
and who have fallen away.”
If it is impossible to fall away, then the parable of the soils is unintelligible.
