We have Four Pillars that express the biblical things that we do as a church: unapologetic preaching, unashamed worship, unceasing prayer and unafraid witness. That last one is about fulfilling the mission Jesus left for us until his coming: go and make disciples. Tell people about him. Tell everyone about him.
In Luke 9:1-9 Jesus sends the 12 apostles out on their first preaching mission. It is the proto-mission for all missions. After his resurrection, in Acts 1:8, he tells all of his followers that they would all be his witnesses everywhere. We all have a responsibility to be preaching the gospel. What does it mean to share the good news of Jesus Christ with boldness?
