This sermon explores the concept of living for God's glory as the ultimate purpose and motivation for Christian life. Dan Huffstutler emphasizes that God is inherently self-centered, which is not only appropriate but necessary for His nature as the supreme being. Christians are called to align their lives with this reality, finding their deepest joy and fulfillment in glorifying God through worship, obedience, and mission. The sermon challenges believers to examine their motivations and to center their lives on God's glory rather than personal gain or human-centered goals.
