How do we know that Jesus is our brother?

Scripture teaches that Jesus Christ is our elder brother through two primary means: His incarnation and our spiritual rebirth. Hebrews 2:14 states that Jesus shared in our humanity, being born into the world as a man, thus connecting with us on a fundamental level. Furthermore, as believers, we experience regeneration, being born of God, which makes us part of God's divine family. In 1 John 3:1, we see that we are called children of God, affirming our relationship with Christ as brothers and sisters in faith and signifying our shared inheritance in the Kingdom of Heaven.
