Salvation of God makes new hearts. The power of God then comes from the inside, overpowering that corruption. Not that we’re perfect, but we have new desires, new longings, new aspirations, new hopes, and new direction. The church then offers the ultimate restraint, a transformed heart. The work of God in salvation is the great restraining work.
