Dear Meditation,
Welcome to the forum.
This is where Christ taught concerning "how" the apostasy (falling away) of a believer happens:
Mat 12:43 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none. 44 Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished. 45 Then goeth he, and taketh with himself SEVEN other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
The spiritual symbol of an unclean spirit represents a spirit which teaches Satan's false truth through lies and deceptions.
Since a new believer remains spiritually blind (Mark 8:21-25) after receiving the Early Rain of the Spirit (the Holy Spirit of Promise, Eph 1:13-14), they cannot replace their worldly false beliefs with the truth of Christ. ONE unclean spirit leaves but comes back with SEVEN more. The number "seven" represents perfection. In this case, the number seven represents the perfection of Satan's lies/deceptions which come to a believer by the indwelling of the spirit of anti-Christ. Now, instead of ONE unclean spirit within the believer, they now have EIGHT. The number eight is a spiritual symbol which represents a new spiritual condition. In this case, the new spiritual condition is worse than the first.
This "worse than the first" spiritual condition causes the believer to become a False Prophet, a Man of Sin, a Minister of Satan, an anti-Christ and a Seven Headed Beast with Ten Horns & Crowns.
Do you have this same understanding? And do you know specifically what lie Satan teaches to a new believer to spiritually kill them (loss of salvation)?
