Is it false teaching to say that becoming a Christian means everything will turn up roses?

Les explains that anyone who promises a rose-petaled pathway if you become a Christian should be chalked off as false teaching, because that has never been the theme of Scripture. He insists that becoming a Christian does not mean everything will turn up roses. Instead, he compares the Christian life to paddling a canoe upstream—one of the toughest jobs on earth—and says it is a constant battle against Satan and the world. Yet the context of 2 Corinthians gives the counter-promise: God comforts and encourages believers in all their tribulation, and the same Lord who permits persecutions and testings provides the strength to go through them. Paul speaks of sufferings abounding, but consolation also abounding by Christ. Early believers under Roman persecution could not glibly talk about their faith; becoming a believer under Paul's preaching was an invitation to persecution.
