Why is Jesus being called our brother significant in the Bible?

The significance of Jesus referring to believers as His brothers is rooted in the deep spiritual relationship established through His redemptive work. In Hebrews 2:11-13, it states that Jesus is not ashamed to call those He sanctifies 'brethren.' This not only signifies a familial bond but emphasizes that believers share in the inheritance and glory that comes through Christ. This relationship captures the profound love and commitment He has for His people, as well as their shared identity in Him.
