2 Corinthians 4:12
“So then death works in us, but life in you.”
Speaking no more of death in the strict sense, but of trials and of rest. 'For we indeed,' he says, 'are in perils and trials, but you in rest; reaping the life which is the fruit of these perils. And we indeed endure the dangerous, but you enjoy the good things; for you undergo not so great trials.'
