The question is the question above in the title. Or is it about apostasy?
Nowhere do I feel that receive the Knowledge of Truth is equal to Accepted Christ and filled with Holy Spirit
I believe that [have received the knowledge of the truth] is simple as hearing the Word of God Preached, the tug of the Holy Spirit's Conviction to Accept Christ, but Denying that Call!
I do not believe that [have received the knowledge of the truth] is Someone Saved Completely and then Choosing to Deny the Experience and God.
