Because I was a pastor of several churches, the subject of the Baptism "of" the Holy Spirit came up often. I had to study, study, study. I had to give Truth to the flock, not just Baptist traditon. I believeI I found a slight difference in the Baptism. The word "of" and the word "in". IMO, The Baptism "of" the Holy Spirit happened at Salvation, just as some posts point out. Now, the Baptism "in" the Holy Spirit is something completely different. When a Christian has matured in his faith, and feels God is leading him to witness for Him in some fashion, he needs to be Baptized "in" the Holy Spirit. The difference is, the first Baptism is for regeneration and placement into the family of God. The second Baptism is to be placed "into" the ministry and power of the Holy Spirit. IMO God gives everyone at least one gift at Salvation. When a believer prays for power to minister, whether they know it or not, they are really asking to be placed into the ministry of the Holy Spirit. And then they realize gifts and power that they never had before.Tongues is simply a tool to be used for prayer and witness, and sometimes a sign. It certainly is not a sign of Salvation. To edify an assembly, they need to understand in their own tongue. Love is the greatest gift known to man.
I could say volumes on this subject but I thought that this simple explanation might prompt others to examine for their information.
Dear Brother.. I am probably a novice! I also believed that "in" and "of" made a significant difference.. But these were originally written in Greek right.. What is your view on the argument put forward by Wayne Grudem? Hope I can share this link,
