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

In Revelation 1:8, Christ identifies Himself as the Alpha and Omega, meaning He is both the beginning and the end of all things. This title reflects His ultimate authority and preeminence over the universe, as stated in Colossians 1:16-17, which declares that by Him all things were created and that all things consist through Him. The Alpha and Omega tells us that Christ is central to God’s eternal plan, encompassing every aspect of creation and salvation, being the embodiment of every promise made in Scripture and the source of life for believers.
