What does the Bible say about love for fellow believers?

1 John 5:1 states, 'Every one that loves him that begat loves him also that is begotten of him,' indicating the necessity of loving other believers as an expression of our love for God. This love transcends differences in creed, denomination, or personal attributes, for it is rooted in the shared identity of being adopted children of God. When we recognize the image of Christ in fellow believers, our hearts are drawn toward them as members of the same family. Thus, our affection for others stems from the divine presence within them—the Father, Son, and Holy Spirit. This divine love not only reveals our spiritual relationship but serves as evidence of our having passed from death unto life in Christ.
