As you said in the previous post, one cannot lose salvation once one has it. It stands for reason that at this time, one cannot quench the spirit.....Keep in mind who Paul, Peter and the other were talking to..The were baby Christians many of whom had fallen (were not justified) This is who He is speaking to in 1 Thessalonians. They had problems in this church because of a fake letter. He was trying to shore them up not to take temptations for others (Judiazers outside the church), their doubts, their rejections of Him, etc...... This was what I was referring to.......
If you are saved (justified), God within you will not let you slide away nor wil He let you Quench the Spirit.
