John carries one major theme throughout most of his biblical writing, ‘Love one another.’ As Christians, Jesus said that we were to be identified by our love. Knowing the love that God has for us and acknowledging that His spirit dwells within the believer, we have no excuse not to love others. It is this love of God in us that unifies the church. It stretches beyond boarders and is understood as a universal language. We can love others because God first loved us.
