When Jesus met His disciples on that hill in Galilee, they wondered just what was going to happen next. Hadn’t Rome demonstrated its hatred of what Jesus was and stood for? Now that He was resurrected, what was going to happen? Jesus stills their ignorance with a direct charge to engage in the mission of Christ through the church to the world.
Their charge is our charge as well. The church that Jesus is building (Matthew16:18, 19) will go out in the authority of Christ to all the nations of the world, teaching the truth of Christ in the power of Christ who will be with them even to the end of the age.
Central to this mission is the truth of God as revealed in Jesus and the Bible. The church that Jesus is building will know, proclaim, obey, and defend this truth. If the church were to turn aside from the truth of God it would cease to be of any value, either to heaven or earth.
