Galatians 2:17-18
17 But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid. 18 For if I build again the things which I destroyed, I make myself a transgressor.
That passage and its context say nothing about loss of salvation.
Why?
Simply stated, for scripture teach the polar opposite to what salvati0on entails, the Bible would be contradictory and without truth.
2 Corinthians 1:22
Who hath also sealed us, and given the earnest of the Spirit in our hearts.
Ephesians 1:13
In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
Ephesians 4:30
30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
In Galatians 2, where do you ever see any mention of one becoming unsealed by Holy Spirit, and where do you ever see the concept of the Father forfeiting His own Holy Spirit by withdrawing salvation from anyone? Given that Holy Spirit is given as the EARNEST, the idea of the Lord forfeiting His Spirit is indeed an evil thought for anyone to entertain, even on the basis of ignorance.
All I can do is make an appeal that you read scripture carefully for what it states, reading each word, word for word, observe the grammatical constructs, and accept what is stated without injections, also observing what is NOT said that tends to arise from the basis of assumption and from the falsehoods of so many false teaching pastors.
