The sermon centers on the vital importance of biblical unity as a reflection of God's glory, rooted in the Holy Spirit and cultivated through humility, love, and self-denial. Drawing from Psalm 133, it emphasizes that true unity—like the anointing oil on Aaron's beard and the life-giving dew of Mount Hermon—is not human effort but a Spirit-sourced reality that glorifies God, strengthens the church, and brings eternal life. The preacher calls the congregation to personal and corporate revival, urging intentional prayer, self-examination, and a Christ-centered focus that prioritizes others over self, especially in preparation for an upcoming evangelistic meeting. Through personal stories and scriptural depth, the message underscores that unity is not uniformity, but a harmonious, Spirit-filled fellowship that enables the church to fulfill its divine purposes: glorifying God, nurturing spiritual growth, upholding truth, and evangelizing the lost.
