How will God complete the mission to seek and save the lost through the preaching of the gospel? What does it mean to have the Holy Spirit? What does the Biblical symbolism of water and rain have to do with the work and outpouring of the Holy Spirit? How can a person know when they have the Holy Spirit? This study answers these questions as we explore the way in which the Holy Spirit worked at Pentecost and what the Bible says about how He will work in the last days. We will also discuss what is needed in order to be prepared to recieve the Holy Spirit! God is ever-ready to give the Holy Ghost to His people... but are we really ready?
