How do we know that God is the only God?

Throughout Scripture, the uniqueness of God is consistently affirmed. For instance, David states in Psalm 116 that the God he worships is the only God there is. This is a foundational tenet of the faith, emphasizing that our God is not just a god among many, but the sovereign Lord of all creation. This truth is pivotal because it shapes our understanding of faith and devotion; genuine faith is anchored in the recognition of God’s singular authority and holiness, which is proclaimed in various Scriptures including Isaiah 45:5, where God declares, 'I am the Lord, and there is none else.'
