The vast majority of Christians have not been helped to see that who they are and what they do everyday in schools, workplaces or clubs is significant to God, nor that the people they spend time with in those everyday contexts are the people God is calling them to pray for, bless and witness to. So we pray for our Sunday school teachers but not for example, for schoolteachers working 40 hours a week in schools among children and adults who on the whole don't know Jesus. We pray for overseas missionaries but not for Christian electricians, builders, shop assistants and managers in our towns... We have simply not been envisioned, resources and supported to share the Good News of Jesus in our everyday contexts.
