In this video,
“Senator Rubio. . .I need to ask two things of you. Number one, Chris Grady, can you stand up? This is my friend who's going into the military. I need you to tell him he's going to live to make it to serve our country. And then we'll get to the other one."
"Absolutely," Rubio replied. "Not only will you live to serve our country, you, and you, and all of you will have a chance to change our country. Change not just our laws but the way we talk about our laws. So absolutely."
Here, this student asks the senator to tell his friend that he’ll live to make it to serve our country. And I don’t understand what it means, especially the part live to.
Does “live” here mean just “to be alive” as we all use in real life? no special meaning? Then what he wants to say here is, “his friend will not going to die from a gun shooting(Because this meeting was held after the shooting accident?) and he’s going to be alive.”? I’m not sure why he’s saying this, I mean, I don’t know what’s implied in his remark.
And also the meaning and role of “to”, which comes next to “live”. Is “to” here used to indicate a “purpose”?
