Why is Jesus important for Christians in their walk of faith?

Jesus Christ is the cornerstone of Christian faith because He embodies the fullness of God's revelation and is the sole mediator between God and humanity. Romans 10:4 states that Christ is the end of the law for righteousness to everyone who believes, illustrating that believers are justified by faith in Him, not by their works. His sacrificial death and resurrection provide believers with salvation, righteousness, and hope of eternal life. In addition, Jesus invites His followers to abide in Him (John 15:4), highlighting the importance of maintaining a relationship with Him as essential for spiritual growth and perseverance in faith. This relationship is predicated upon recognizing Him as both Lord and Savior, which transforms the believer's life.
