All theology is also spirituality, in the sense that it has an influence, good or bad, positive or negative, on its recipients’ relationship or lack of relationship to God. If our theology does not quicken the conscience and soften the heart, it actually hardens both; if it does not encourage the commitment of faith, it reinforces the detachment of unbelief; if it fails to promote humility, it inevitably feeds pride. So one who theologizes in public, whether formally in the pulpit, on the podium or in print, or informally from the armchair, must think hard about the effect his thoughts will have on people — God’s people, and other people. Theologians are called to be the church’s water engineers and sewage officers; it is their job to see that God’s pure truth flows abundantly where it is needed, and to filter our any intrusive pollution that might damage health (J.I. Packer, A Quest for Godliness, 15).

Since this is the case, then in a real sense we are all theologians, good or bad. Every conversation and opinion must be reflective of the truth as it is in Christ, especially the pulpit. Every thought. Every conversation. Every opinion.
