How do we know that Christ's deity is true?

The affirmation of Christ as Alpha and Omega in Revelation highlights His unique and full deity. In Isaiah 44:6, God declares, 'I am the first and I am the last; beside me there is no God.' This direct correlation identifies Jesus with God's eternal nature, emphasizing that He is not merely a distinct person but fully God, co-existing eternally with the Father and the Holy Spirit. Additionally, such identification throughout Scripture reinforces the understanding that Christ's role transcends mere prophet or priest; He embodies the fullness of the Godhead and is the perfect fulfillment of God's covenant promises.
