Excellent word here on the church, the pastor and political activism.
Don’t press the organization of the church or her pastors into political activism. Pray that the church and her ministers would feed the flock of God with the word of God centered on the gospel of Christ crucified and risen. Expect from your shepherds not that they would rally you behind political candidates or legislative initiatives, but they would point you over and over again to God and to his word, and to the cross.
Please try to understand this concluding point. When I warn you against politicizing me, or politicizing the institution called Bethlehem, or the church in general, I do so not to diminish her power but to increase it. The impact of the church for the glory of Christ and the good of the world does not increase when she shifts her priorities from the worship of God and the winning of souls and the nurturing of faith and raising up of new generations of disciples. It doesn’t. It feels in the moment that it does. “Look at how many people showed up for the rally!” Or “Look how many signatures in that church they got!” Or “Look how that committee is functioning!” It feels powerful, but give it a generation. And little by little, that vaunted power bleeds away the very nature of the church and its power. – John Piper
