Why is knowing who Jesus Christ is important for Christians?

Understanding the identity of Jesus Christ is paramount for Christians because He is the foundation of their faith. He is God incarnate, the one who reconciles sinners to God by bearing the penalty for sin (Hebrews 1:2-3). This relationship directly impacts a believer's assurance of salvation and their ability to grasp the depth of God's grace and love, as Christ is the means by which they are accepted before a holy God (Ephesians 1:6). Therefore, comprehending His nature and work enables believers to live in grateful obedience and love.
