Sermon on the MountStuart Jones Early in His ministry Jesus delivered the most famous sermon ever, the Sermon on the Mount. What Jesus said to those listening that day seemed almost like up was down, right was left and white was black. Jesus taught about subjects such as prayer, justice, care for the needy, handling the religious law, divorce, judging other people, salvation and much more. What He said didn’t coincide with what most of the listeners had thought about those subjects. Jesus made it clear that His followers should live in a noticeably different way than other people.
