Jesus speaks to his churches. He has a vision for how Christians are to live and think and love. And he has a vision for what local churches should care about and be committed to. And so he sends a letter to the churches to encourage them where they need encouragement, and correct them where they need to be corrected.
And we need this same encouragement and correction today. The challenges that the first churches face are still the challenges that we face today.
Jesus calls his churches to rise up, stand firm, and keep going—even when their culture is challenging or hostile to them. And the challenges that these churches faced back then are still relevant to us today.
