John 11:25-27 TNIV (Today's New International Version)
25 Jesus said to [Martha], "I am the resurrection and the life. Anyone who believes in me will live, even though they die; 26 and whoever lives by believing in me will never die. Do you believe this?"
27 "Yes, Lord," she told him, "I believe that you are the Messiah, the Son of God, who was to come into the world."
John 14:2-3 NRSV
In my Father’s house there are many dwelling-places. If it were not so, would I have told you that I go to prepare a place for you? And if I go and prepare a place for you, I will come again and will take you to myself, so that where I am, there you may be also.
2 Corinthians 5:1-9 TNIV
1 For we know that if the earthly tent we live in is destroyed, we have a building from God, an eternal house in heaven, not built by human hands. 2 Meanwhile we groan, longing to be clothed with our heavenly dwelling, 3 because when we are clothed, we will not be found naked. 4 For while we are in this tent, we groan and are burdened, because we do not wish to be unclothed but to be clothed with our heavenly dwelling, so that what is mortal may be swallowed up by life. 5 Now the one who has fashioned us for this very purpose is God, who has given us the Spirit as a deposit, guaranteeing what is to come. 6 Therefore we are always confident and know that as long as we are at home in the body we are away from the Lord. 7 We live by faith, not by sight. 8 We are confident, I say, and would prefer to be away from the body and at home with the Lord. 9 So we make it our goal to please him, whether we are at home in the body or away from it.
1 Corinthians 15 (selected texts) TNIV
12 But if it is preached that Christ has been raised from the dead, how can some of you say that there is no resurrection of the dead? 13 If there is no resurrection of the dead, then not even Christ has been raised. 14 And if Christ has not been raised, our preaching is useless and so is your faith. 15 More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised. 16 For if the dead are not raised, then Christ has not been raised either. 17 And if Christ has not been raised, your faith is futile; you are still in your sins. 18 Then those also who have fallen asleep in Christ are lost. 19 If only for this life we have hope in Christ, we are to be pitied more than all others. 20 But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep. 21 For since death came through a human being, the resurrection of the dead comes also through a human being. 22 For as in Adam all die, so in Christ all will be made alive...
36 What you sow does not come to life unless it dies. 37 When you sow, you do not plant the body that will be, but just a seed, perhaps of wheat or of something else. 42 So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; 43 it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; 44 it is sown a natural body, it is raised a spiritual body. If there is a natural body, there is also a spiritual body....
50 I declare to you, brothers and sisters, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. 51 Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52 in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. 53 For the perishable must clothe itself with the imperishable, and the mortal with immortality. 54 When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: "Death has been swallowed up in victory."
55 "Where, O death, is your victory? Where, O death, is your sting?"
56 The sting of death is sin, and the power of sin is the law. 57 But thanks be to God! He gives us the victory through our Lord Jesus Christ.
58 Therefore, my dear brothers and sisters, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain.
1 Thessalonians 4:13-18 TNIV
13 Brothers and sisters, we do not want you to be uninformed about those who sleep in death, so that you do not grieve like the rest, who have no hope. 14 We believe that Jesus died and rose again, and so we believe that God will bring with Jesus those who have fallen asleep in him. 15 According to the Lord's word, we tell you that we who are still alive, who are left till the coming of the Lord, will certainly not precede those who have fallen asleep. 16 For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17 After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever. 18 Therefore encourage one another with these words.
Philippians 1:21-24 TNIV
21 For to me, to live is Christ and to die is gain. 22 If I am to go on living in the body, this will mean fruitful labor for me. Yet what shall I choose? I do not know! 23 I am torn between the two: I desire to depart and be with Christ, which is better by far; 24 but it is more necessary for you that I remain in the body.
2 Timothy 4:6-8 TNIV
6 For I am already being poured out like a drink offering, and the time for my departure is near. 7 I have fought the good fight, I have finished the race, I have kept the faith. 8 Now there is in store for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day—and not only to me, but also to all who have longed for his appearing.
Psalm 116:15 TNIV
15 Precious in the sight of the LORD is the death of those faithful to him.
