Do Muslims Respect Jesus?

Our Muslim friends often claim that Jesus is highly honored and respected in Islam. But then they tell us that Jesus' message was corrupted (by Allah himself, along with others), that Jesus' followers abandoned his teachings, and that we needed Muhammad to come along to accomplish what Jesus couldn't accomplish. But this means that Jesus didn't actually accomplish anything that lasted. How can Muslims say they respect Jesus when they portray him as a complete failure?
