The word philadelphia is translated “brotherly love.” Because Christians belong to the same family, and have the same Father, they should love one another. In fact, we are “taught of God to love one another.” God the Father taught us to love each other when He gave Christ to die for us on the cross. “We love, because He first loved us” (1 John 4:19). God the Son taught us to love one another when He said, “A new commandment I give unto you, that ye love one another” (John 13:34). And the Holy Spirit taught us to love one another when God poured out the love of God in our hearts (Romans 5:5) when we trusted Jesus Christ.
