Why is it important for Christians to understand Jesus as the first and last?

Recognizing Jesus as the first and last is fundamental to Christian faith as it encapsulates His sovereignty over all things. This acknowledgment provides profound assurance that He governs both the beginning and the end of history and personal lives. As emphasized in Revelation 1:17-18, Jesus reassures His followers, saying 'Fear not,' which underscores the peace that comes from this knowledge. Moreover, this truth can serve as a source of comfort during trials, reminding believers that the same Christ who called them to Him is with them through all of life's circumstances, guiding them from beginning to end.
