What does it mean that Jesus is the first and the last?

The designation of Jesus as the first and the last illustrates His eternal nature and unparalleled authority. As the first, He stands at the inception of creation, actively involved in bringing all things into existence, confirming His role as God. As the last, He signifies that all things will ultimately conclude in Him. This title assures believers that He is both the means by which creation was made and the endpoint to which history is directed. Thus, believers can trust that their lives are part of a divine plan that spans from the beginning to the end, anchored in His faithful presence.
