I am the Alpha and the Omega, the Beginning and the End. In Revelation He is shown as the conqueror of sin, death, and hell. It is He who has all authority in heaven and on earth. It is the Alpha and Omega who makes promises that are guarantees.
Politicians make promises and try to do their best.
Jesus makes eternal promises and delivers. It's a day to celebrate the power and glory of our Lord Jesus, the Alpha and Omega.
