People don't receive power from the Holy Spirit today like the apostles did after Pentecost. We're sealed by the Holy Spirit after we accept Jesus as our Lord and Savior. The Holy Spirit intercedes for us. The Holy Spirit convicts us of sin and reveals biblical truth to us as we study the Bible. At times the Holy Spirit guides us directly but few people experience that on a regular basis. I believe that the Holy Spirit uses us more and more as we grow in obedience and righteousness.
