The Holy Spirit Baptism

Many people have said that when a person gets born again, although they use the word saved, he is automatically filled with the Holy Spirit. I have even heard some Pentecostal preachers say that this is true and, if they want, they can ask God for their prayer language. I don't know where they got that idea because there is nothing in the Bible to back either of those statements. In this book I quoted the Bible and have given you reasons for the Holy Spirit baptism; but you must make the ultimate decision whether it's necessary for you or not.
