The sermon highlights the crucifixion and resurrection of Christ, followed by the pouring out of the Spirit on the apostles on Pentecost in Jerusalem. Beyond that, the gift of the Spirit was (is) available to everyone who believes and is baptized and who follows in Christ's footsteps. Our challenge in our walk with God is to be open to the will of God in His revealed truth, to be as true to that as possible without adding to or taking away from the conduct He desires. We are to be faithful. He wants us to be united as a family. He wants us to be shining examples of His truth, despite the inevitable rejection this will often bring us from the non-believers.
