In this passage, John reminds us that true belief is in Christ Jesus—how in true faith we come to love the Father, and here John reminds us, that if we love the Father, then we also love the people we belong to. In fact, John even goes on to say you can't love God and not love all of His children. But the love of God is a holy love, and in order to love like God we have to understand God's sacrificial love. (1 John 5:1–12)
