How do we know that Jesus is not ashamed to call us brethren?

The truth of Jesus not being ashamed to call us brethren is explicitly found in Hebrews 2:11. This passage reveals that Christ identifies intimately with those He saves, describing them as part of His family. This connection emphasizes His love and acceptance. It assures believers of their place in the family of God, which is grounded not in their merit but in Christ's sacrificial act. Furthermore, Romans 8:29 elucidates that those who God foreknew He predestined to be conformed to the image of His Son, thus reinforcing the notion that all whom He calls are indeed His brethren.
