You are speaking of the so-called Baptism of the Holy Spirit. I don't believe that is what the question is asking. When we get saved, we are all given a measure of the Holy Spirit... In that instance, my point is correct and stands as written... The so-called Baptism of the Holy Spirit is a different HS experience where, yes, you will know when that event occurred...When I received the Holy Spirit is was an EXPERIENCE. There is no way NOT to know. Some only believe in Him theologically, but have never been baptized in the Holy Spirit; they only think they have Him inside. It was quite a shock to me to realize that for 30 years of going to church, I wasn't even born again - until I was. Life changed drastically.
