I agree
@Hakawaka. You can have a completely washed and white robe, receive the gift of the Holy Spirit, then fall from the faith once delivered to the saints. You will feel like you are in the field with swine feeding on dirty corn husks. You will feel unclean, backslidden, abandoned and filthy. The embarrassment will be so severe that you will be afraid to return back to the Father because you are unworthy.
Ask me how I know....
At age 22 in 1986, with the heart of a child, I had hands laid on me by spirit filled believers and with the faith once delivered to the saints, I received the baptism of the Holy Spirit. Twenty two years of sin and burden were removed from me and I felt the hand of God upon me. One week later, I was immersed in a pond on a mountain top in Northeastern Pennsylvania.
But, after three years, like the parable of the sower Matthew 13, either it was stolen from me by the adversary, it was sewn on rocky ground or tribulation came that I could not stand against. I was in danger of losing salvation.
I had to repent and continue to repent daily because I know I was born a sinner and my physical nature is to sin. The Holy Spirit of God and mind of Christ that dwells in me are all that is good.
If it were not for the parable of the prodigal son, I would not know I could return. Luke 15:18-32
A person can lose salvation if they backslide and continue in sin. 1 Corinthians 6:
9Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
11And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
A believer may not know this until they fall from grace.
Experience is a harsh teacher, but when a lesson is learned that way, it is not easily forgotten.
