In today's reading 1 from Acts 19, Paul found some disciples in Ephesus. He baptized them in the name of the Lord Jesus. When Paul laid his hands on them, the Holy Spirit came upon them, and they spoke in tongues and prophesied. The Holy Spirit is to be experienced. If you do not feel anything, how can you be sure that it is the Holy Spirit, not yourself, who prompts you to do something. There has to be come kind of personal connection between the Spirit and you, for the Lord Spirit is the living God. Again, to know that it's always the Spirit motivating you, seek to attain union with God and you'll experience the presence of the indwelling Holy spirit within.
