I tremble for those who are preaching the truth – the truth as it is in Jesus, the gospel in its simplicity, in its purity, in its fullness – but preaching it “in persuasive words of wisdom” and not “in demonstration of the Spirit and of power” (1 Cor 2.4), preaching it in the energy of the flesh and not in the power of the Holy Spirit. There is nothing more deadly than the gospel without the Spirit’s power.
