As a child I remember travelling on steam trains. The engine takes hot steam from a boiler, which expands under pressure and the heat energy is converted into work. It’s much like the life of every disciple. We require the fire of God’s love in the Holy Spirit (Acts 2:3) to inspire us to live creative lives of service. The fire is maintained by encountering Christ in Scripture and the prayer such reading inspires to rise from our lips, in worship and intercession.
