Erlo Stegen emphasizes the profound invitation at the end of Revelation for all to 'come' to the Lord, highlighting the unity between the Holy Spirit and the Bride, which is the Church. He stresses the importance of obeying the Spirit's call and the necessity of being filled with the Spirit to truly echo this invitation. The sermon underscores the significance of accepting the free gift of life-giving water from Jesus and the urgency of longing for His return. Stegen warns against altering God's Word, reminding listeners of the serious consequences of tampering with Scripture. As the New Year begins, he calls for self-reflection on one's relationship with Christ and the invitation to be part of His Bride.
