Though there’s much to say, I found this thought from Jonathan Leeman a good and necessary place to start.
Christian’s politics always begins with Jesus. He’s the King of kings and Lord of lords. And we know his will through his Word.
A Christian’s politics proceeds through the spoken evangelistic word: “The King is coming to judge all transgressors. Repent and believe, and he will graciously pardon.”
A Christian’s politics then takes root in the individual heart. Only a heart that’s been remade by the Spirit of God will no longer seek to lord it over others, but will extend mercy even as it has received mercy.
Then, remarkably, a Christian’s politics should become visible in the life and fellowship of the local church—both in its teaching and in its fellowship. Whether you’re a member of this party or that party, the local church is where we learn to love our enemies, forsake our tribalism, and beat our swords into ploughshares and spears into pruning hooks. Here is where we tutor one another in the righteousness and justice of God. Here is where the righteousness and justice of God become tangible, credible, and believable for the onlooking nations.
Every week that a preacher stands up to preach he makes a political speech. He teaches the congregation “to observe all” that the King with all authority in heaven and on earth has commanded (Matt. 28:20). He strives to shape their lives in the way of the King’s law. We then declare the King’s judgments in the ordinances, embrace the King’s purposes in our prayers, and echo the King’s joy and mourning in our songs.
