Why is it important for Christians to understand who Christ is?

Christ's identity as the 'Messiah' and 'Christ' is foundational for the Christian faith, as seen in the preaching of Paul in Acts 17. He emphasizes that the Jesus he is preaching is the Christ who fulfills the entire biblical narrative. By recognizing Christ as the anointed prophet, priest, and king, believers acknowledge that He is the one who perfectly represents God to humanity and humanity to God. Understanding this enables Christians to appreciate the significance of His sacrificial death and glorious resurrection. Additionally, it affirms the assurance of their salvation, as 1 John 5:1 explains that 'whoso believeth that Jesus is the Christ is born of God.' Thus, a firm grasp of who Christ is enriches one's faith and understanding of divine grace.
