In the sermon, Pastor focuses on the significance of the Holy Spirit in the life of believers as emphasized in Acts 5:32 and Luke 11:13. He points out that the Holy Spirit is granted to those who ask in faith and obey God's Word. Pastor elaborates on the transformative power of the Holy Spirit, claiming that only through surrender to Jesus can one receive the power to overcome sin and live righteously. He underscores that true obedience comes from a genuine relationship with Christ, which leads to sanctification and a personal commitment to live according to God’s commandments.Transitioning to a deeper exploration of the prophecies found in Revelation, particularly Revelation 10, Pastor identifies the mighty angel representing Christ and examines the symbol of the cloud and the rainbow, connecting them to the power in the Advent movement. He explains that the cloud signifies the Second Coming of Christ, and the rainbow symbolizes God’s covenant with humanity, hinting at the doctrines presented in the church and the importance of recognizing them. Pastor warns against the dangers of being spiritually dry or complacent in one’s faith, urging believers to fully engage with the teachings of Scripture and embrace the Holy Spirit’s leading in their lives. He concludes with a call for deeper understanding and recognition of the Holy Spirit's work in preparing the church for the coming of the Lord.
