Why is the concept of Jesus being the Christ important for Christians?

For Christians, recognizing Jesus as the Christ is crucial as it encompasses the foundation of their faith and salvation. This belief is not merely historical; it signifies a profound relationship with the Savior, ensuring that all promises made by God are realized through Him. As the Christ, Jesus embodies the fulfillment of the law and the prophets, which means that through His death and resurrection, believers are assured of their salvation. His declaration, 'It is finished' (John 19:30), signifies that the work of salvation is complete. In essence, knowing Jesus as the Christ assures us of our identity as His children and our eternal security in Him, as defined in John 10:28, where He affirms that He will lose none of those given to Him by the Father.
