How do we know God is the one true God?

Psalm 115 clearly states, 'Our God is in the heavens; He has done whatsoever He has pleased.' This highlights His sovereignty and authority over all creation. All other so-called gods are man-made and cannot fulfill the divine attributes that characterize the one true God. Throughout Scripture, God asserts His uniqueness and lordship, demonstrating that He is the only one who can save, heal, and deliver His people. His actions in history and His fulfillment of the promises in Scripture further affirm His true identity.
