The Pastors High Calling to lead in Heralding the Gospel and Open Air Preaching

‎Christians are to be in submission to the authorities in the local church that strive hard to labor faithfully.
‎So what are these leader to do in regard to witnessing and heralding the gospel. We are to lead you in the charge, we are to be the ones who lead by example. ‎Pastor Jeff Noblit Grace Life Church of the Shoals calls this Modeling. ‎Pastor's your congregation will not share the gospel if you are too scared to lead them out the door. ‎If you are not obedient to say with Paul Philippians 3:17
C.H. Spurgeon said No sort of defense is needed for preaching out-of-doors; but it would need very potent arguments to prove that a man had done his duty who has never preached beyond the walls of his meetinghouse. A defense is required rather for services within buildings than for worship outside of them. Apologies are certainly wanted for architects who pile up brick and stone into the skies when there is so much need for preaching rooms among poor sinners down below. Defense is greatly needed for forests of stone pillars, which prevent the preacher from being seen and his voice from being heard; for high-pitched Gothic roofs in which all sound is lost, and men are killed by being compelled to shout till they burst their blood-vessels; and also for the willful creation of echoes by exposing hard, sound-refracting surfaces to satisfy the demands of art, to the total overlooking of the comfort of both audience and speaker.
The great benefit of open-air preaching is that we get so many newcomers to hear the Gospel who otherwise would never hear it. The Gospel command is, "Go ye into all the world, and preach the gospel to every creature," but it is so little obeyed
