How do we know Christ's importance in Christianity?

We understand Christ's importance from Scripture, which portrays Him as the focal point in both the Old and New Testaments. John 1:1-3 highlights that He was present with God in the beginning, and Colossians 1:16 makes clear that all things were created by Him and for Him. This indicates that Christ is not just an aspect of our faith but the very purpose of existence itself. His work fulfills the Old Testament sacrifices and prophecies, as they ultimately point to the one true Savior. When we see that everything in the Bible revolves around Christ, we begin to grasp why knowing Him is of utmost importance for every Christian.
