Why is union with Christ important for believers?

Union with Christ is a theological concept that underscores the intimate relationship between Christ and believers. This union is foundational to Christian faith as it signifies that believers are identified with Christ in His death, burial, and resurrection. In Esther 7, Esther's identification with her people mirrors this union, illustrating how Jesus identifies with His Church. When Christ died for His people, He bore their sins, demonstrating the depth of His love and commitment to them. Romans 6:5 states, 'For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his.' Such an assurance provides believers with hope and stability in their walk of faith.
