This is our final installment in the Holy Spirit series, and to wrap things up there are three key words/ideas which help distill all that we've look at and learned. The Holy Spirit's purpose is to mediate the presence, the power, and the promises of Jesus Christ in his followers. This sermon unpacks the Spirit's role in establishing the presence of Christ in the hearts of beleivers, in giving them power to do the work Jesus gave them to do, and to serve as a guarantee of the believer's inheretince through the promises of God in Christ.
