Why is the concept of Christ's pre-existence important for Christians?

The pre-existence of Christ, as articulated in John 1:1, states, 'In the beginning was the Word, and the Word was with God, and the Word was God.' This establishes Jesus not merely as a temporal figure but as eternal and co-existent with the Father. Understanding Christ's pre-existence is pivotal in recognizing the full scope of His mission and His divine nature. It underscores that He was not created, but rather, He has always been and was sent into the world as the fulfillment of God's redemptive plan. This doctrine assures believers of His ultimate authority and the sufficiency of His sacrifice for salvation.
