The word Alpha means first, and Omega means last. God is the Alpha and the Omega. This means that Jesus is the first and the last. He knows the end from the beginning. When God calls Himself as the Alpha and the Omega in Revelation 1:8, 21:6 and 22:13, He means that He is the beginning and the end. He existed at the beginning of the universe, and He has no end. He, Himself is the end. Sounds funny! Yes, but that is the truth.
As a Christian, it is vital to acknowledge that everything started with Him and will end with Him. John 1:3 says that all things were made through Him; nothing was made that was made without His Word. In the book of Revelation, He promises that the end shall come and all the universe shall be burnt to ashes. What should come to your mind as you go through such stories is that you and I are God’s own creation, created to fulfill a purpose. Every time you feel confused about life, you’ve got to go back to the Creator who knows your end from your beginning. The more you know Him, the more you know yourself.
As the Alpha and the Omega, God desires that we worship Him in truth and spirit without blame. In Revelation 1:8, He says that He is the Alpha and the Omega, the one who was, who is and is to be. He is the same yesterday, today and forever. Therefore, everyone should understand that whatever He says about Himself never changes. He does not lie. He defines our life. Being the Alpha and the Omega, He is the most supreme, and so we should always understand that we live under His power, whether we believe in Him or not. We can all worship Him and thank Him for being our Alpha and Omega.
