and no person who continues to live and believe in me will ever die at all. Do you believe this?" She said to Him, "Yes, Lord, I believe that you are the Christ, the Son of God, who was to come into the world." On saying this she went back and called her sister Mary, whispering to her, "The Teacher is here and is asking for you." As soon as she heard it, she jumped up and started to Jesus, for He had not yet come into the village, but He was still at the place where Martha had met Him. So the Jews who were with her in the house sympathizing with her, when they saw Mary jump up and go out, followed her, because they supposed that she was going to the grave to pour out her grief there. When Mary came where Jesus was and saw Him, she threw herself at His feet, and said, "Lord, if you had been here, my brother would not have died." So when Jesus saw her weeping and the Jews who had come with her weeping too, He sighed in sympathy and shook with emotion, and asked, "Where have you laid him?" They answered, "Lord, come and see." Jesus burst into tears.

Yes, I repeat it, anything you ask for as bearers of my name I will do it for you.

Also we do not want you to have any misunderstanding, brothers, about those who are falling asleep, so as to keep you from grieving over them as others do who have no hope. For if we believe that Jesus died and rose again, then through Jesus, God will bring back with Him those who have fallen asleep. For on the Lord's own authority we say that those of us who may be left behind and are still living when the Lord comes back, will have no advantage at all over those who have fallen asleep.read more.
For the Lord Himself, at the summons sounded by the archangel's call and by God's trumpet, will come down from heaven, and first of all the dead in union with Christ will rise, then those of us who are still living will be caught up along with them on clouds in the air to meet the Lord, and so we shall be with the Lord forever. So continue encouraging one another with this truth.
