Proverbs 3:11 “My son, despise not the chastening of the Lord; neither be wary of his correction: 12 For whom the Lord loveth He correcteth; even as a father the son in whom he delighteth.”
In Philippians Paul writes in 1:6 “Being confident of this very thing, that he which began a good work in you will perform it until the day of Jesus Christ”
Romans 7 and 8 are great chapters of the struggle Paul had with sin and the flesh. Remember, this is the person God chose to write the letters that are in a major part of The Bible and even he struggled considerably with sin.
Always remember this comforting verse from Romans 8 35-39 “Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?” “As it is written, for thy sake we are killed all the day long; we are accounted as sheep for the slaughter.” “Nay in all these things we are more than conquerors through him that loved us” “For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come” ” Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.”
If you are going through a correction because you have backslidden it will not be easy. Correction is designed that way. Be thankful. You ARE going to get through it, God is faithful without end.
You may be dealing with whether you have done something that cannot be forgiven. I can assure you your sins are forgiven. Remember Romans chapter 8. The Bible does not say Jesus died for all sins “except”. Do not think that your situation is different than anybody elses. We are all sinners, period. Keep fighting the good fight. It’s the trying that matters.
Can one lose The Holy Spirit? NO!
The Bible clearly states:
John 14:16 “And I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever;”
Ephesians 1:13 “In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom after that ye believed, ye were sealed with the Holy Spirit of promise,”
Once the Holy Spirit indwells a person it is forever. John 14:16 clearly states this. Correction is difficult but you will get through it, God will see to it. Keep praying for guidance. God is faithful.
