2 Timothy 1: Paul is near death in a prison.

 Paul is in a prison for the second time in Rome. Nero is Caesar. He is near death. We read:

11-12 This is the Message I’ve been set apart to proclaim as preacher, emissary, and teacher. It’s also the cause of all this trouble I’m in. But I have no regrets. I couldn’t be more sure of my ground—the One I’ve trusted in can take care of what he’s trusted me to do right to the end.

Imagine that Paul were not certain about his resurrection after death, would he be in peace in prison? Probably he were thinking about if what he has done was right or wrong. However, Paul trusted in Jesus and received the treasure/gospel that he was obliged to preach.
