Could you really die for Jesus?

If today's government became anti-christianity like the Romans during the early days of the church and they were killing Christians for their faith in Jesus and you were asked to deny Jesus to save your life, would you deny and save your life or would you give up your life? Let's say this happened tomorrow. What would your response be?

EDIT: 99% of you said you would happily give up your life. I've said the same thing all my Christian life. But I had a dream recently where I was on the verge of death(I think I did die in the dream and woke up) and it was so starkly terrifying that it got me thinking. Also, being tortured to death or seeing your loved ones suffering I'm sure can mess with your mind as well.
