What makes our faith in Jesus Christ genuine? In this section of 1 John we can understand that it’s not just that we say we’re believers, but that we act out our faith. John repeatedly says You’ve already heard this. Yet, as the aged Apostle he tells them to live out the message Jesus gave by loving each other! Challenges to our love comes from those close to us. Just like when Cain murdered his brother Abel. Why? Because he was jealous of his righteous deeds.
