Martyn Lloyd-Jones on Holy Spirit

But the danger is to think of the baptism of the Holy Spirit only in terms of gifts rather than in terms of something much more important, which is this: the mark, ultimately, and proof of whether we have received the Spirit or not is surely something that happens in the realm of our spiritual experience. You cannot read the New Testament accounts of the people to whom the Spirit came, these people upon whom He fell, or who received as the Galation Christians and all these others had done, without realizing that the result was that their whole spirit was kindled. The Lord Jesus Christ became real to them in a way that He had never been before . . . the result was a great love for Christ shed abroad in their hearts by the Holy Spirit.
