The Holy Spirit is Jesus' greatest gift to believers, enabling us to experience God's presence everywhere and always. As the Spirit of Truth, He glorifies Jesus and rests upon every believer with God's glory. The Spirit empowers our worship, gives strength to endure trials, and enables gospel witness. He produces spiritual fruit in our lives and distributes gifts to every believer. To experience the Spirit's fullness, we must spend time in God's Word, practice silent prayer and gratitude, and walk in obedience to God's commands.
