Why did Jesus preach on the open ground, instead of in the synagogues or Temple?
Though Jesus preached in the synagogues and the Temple, he had to move to the lakeshore of the Sea of Galilee and other open areas because of the resentment of the conservative Jews who opposed him. However, he had the advantage of accommodating the enormous crowd on the open ground that no synagogue could contain. The Gentiles, the Publicans, and others who were ineligible, or uninterested in the synagogue service, could also meet Jesus by the lakeshore. Besides, he could avoid the disturbance of the antagonists in the synagogue.
