How do we know that Jesus is both God and Savior?

The testimony of scripture affirms that Jesus is fully God and fully man. In Revelation 22:16, Jesus declares Himself to be both the root and offspring of David, indicating His eternal divinity and His humanity. Additionally,1 Timothy 3:16 states that 'God was manifest in the flesh,' making it clear that the incarnation is a miraculous act where the Creator entered into His creation. The prophecies in Isaiah, such as Isaiah 9:6, refer to the coming Messiah as the Mighty God and Everlasting Father, further establishing that the child born to Mary was indeed God Himself, coming to save His people.
