From The Crucifixion of Ministry by Andrew Purves:
To ministers, let me say this as strongly as I can: preach Christ, preach Christ, preach Christ. Get out of your offices and get into your studies. Quit playing office manager and program director, quit staffing committee’s, and even right now recommit yourselves to what you were ordained to do, namely the ministry of Word and sacraments. Pick up good theology books again: hard books, classical texts, great theologians. Claim the energy and time to study for days and days at a time. Disappear for long hours because you are reading Athanasius on the person of Jesus Christ or Wesley on sanctification or Augustine on the Trinity or Calvin on the Christian life or Andrew Murray on the priesthood of Christ. Then you will have something to say that’s worth hearing.
