Part 2 of What We Believe: The Basics of Christian Doctrine and the Baptist Faith. The lesson aims to present a comprehensive theological exploration of God's nature, beginning with the assumption of God's existence as foundational to Scripture and human reason, supported by logical arguments from creation, design, and moral awareness. It then unfolds the doctrine of the Trinity—not as a term found in Scripture but as a vital concept affirming one God in three co-equal, co-eternal persons: Father, Son, and Holy Spirit—each fully God, distinct in role yet unified in essence, with the Father initiating, the Son accomplishing, and the Spirit applying divine work. The lesson emphasizes God's infinite, unchanging, holy, self-existent, and sovereign attributes—omnipresent, omniscient, omnipotent—revealed through Scripture and experienced in worship, while underscoring that God is a personal Spirit with thoughts, emotions, and desires, capable of sorrow over human sin, yet eternally loving, just, merciful, and faithful. Ultimately, the purpose is to reveal God's greatness and nearness, inviting awe, humility, and trust in a God who is both infinitely beyond humanity and intimately concerned for it.
