In his sermon "Heart of Worship" on Psalm 95, Ross emphasizes that true worship involves a heart fully surrendered to God. Worship is more than singing; it is a deep devotion, reverence, and adoration expressed through our entire lives. Ross explains that surrender, akin to raising a white flag in battle, means submitting to God's authority. He highlights recognizing who God is—our Creator, Shepherd, and King—and responding with worship, humility, and obedience. Using the Israelites' failure to trust God as a cautionary tale, Ross urges us to embrace surrender and trust in God. Inspired by Jesus' sacrificial love, he calls for complete surrender, leading to eternal life and present blessings of peace, guidance, and protection. Ross encourages both new believers and seasoned Christians to evaluate their lives and fully surrender to God.
