How do we know we are brothers and sisters in Christ?

The concept of brotherhood among believers is deeply rooted in Scripture. In John 1:12, we see that those who receive Jesus are given the right to become children of God. This establishes God as our Father and us as siblings in the faith. Hebrews 2:11 reinforces this by stating that Jesus is not ashamed to call believers His brethren. Consequently, our shared identity as children of God is evidenced through our love for one another, aligning with 1 John 3:10, which distinguishes the children of God from the children of the devil based on their actions, particularly their love for the brethren.
