What does the Bible say about Christ being Alpha and Omega?

In Revelation 1:8, Jesus declares, 'I am Alpha and Omega, the beginning and the ending.' This phrase highlights the eternal nature of Christ, affirming that He is the source of all creation ('the beginning') and the ultimate fulfillment of God's redemptive plan ('the ending'). In this context, Jesus emphasizes His sovereignty over history, demonstrating that all things begin and end in Him. This understanding comforts believers, reminding us that no matter the trials faced in life, Christ is in control of all processes of time and eternity.
