1 Thessalonians 5:11

Dost thou see how everywhere he puts the common salvation into the hands of each individual? "Exhorting one another daily" (he says) "while it is called To-day." Do not then cast all [the burden] on your teachers; do not [cast] all upon them who have the rule over you: ye also (he means) are able to edify one another. Which also he said in writing to the Thessalonians, "Edify one another, even as also ye do." And again, "Comfort one another with these words." This we also now exhort you.… If ye be willing, ye will have more success with each other than we can have. For ye both are with one another for a longer time, and ye know more than we of each other's affairs, and ye are not ignorant of each other's failings, and ye have more freedom of speech, and love, and intimacy; and these are no small [advantages] for teaching, but great and opportune introductions for it: ye will be more able than we both to reprove and to exhort. And not this only, but because I am but one, whereas ye are many; and ye will be able, however many, to be teachers.

"That, whether we wake or sleep, we should live together with Him. Wherefore exhort one another, and build each other up, even as also ye do." And again, "whether we wake or sleep"; by sleep there he means one thing, and here another. For here, "whether we sleep" signifies the death of the body; that is, fear not dangers; though we should die, we shall live. Do not despair because thou art in danger. Thou hast a strong security. He would not have given His Son if He had not been inflamed by vehement love for us. So that, though thou shouldest die, thou wilt live; for He Himself also died. Therefore whether we die, or whether we live, we shall live with Him. This is a matter of indifference: it is no concern of mine, whether I live or die; for we shall live with Him.
