We do not go to heaven at death unless we are ressurected, we go to the grave until we are called out of the grave of the second coming, here is a excerpt from what tall73 wrote, it is very straight forward:
"The human soul is not immortal
EZE 18:3 "As surely as I live, declares the Sovereign LORD, you will no longer quote this proverb in Israel. 4 For every living soul belongs to me, the father as well as the son--both alike belong to me. The soul who sins is the one who will die.
PS 26:9 Do not take away my soul along with sinners, my life with bloodthirsty men,
PS 116:8 For you, O LORD, have delivered my soul from death, my eyes from tears, my feet from stumbling,
PR 23:13 Do not withhold discipline from a child; if you punish him with the rod, he will not die.
Punish him with the rod and save his soul from death.
MT 10:26 "So do not be afraid of them. There is nothing concealed that will not be disclosed, or hidden that will not be made known. 27 What I tell you in the dark, speak in the daylight; what is whispered in your ear, proclaim from the roofs. 28 Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell.
The soul is the dust + the breath of life. A soul is a human being.
GE 2:4 This is the account of the heavens and the earth when they were created. When the LORD God made the earth and the heavens-- 5 and no shrub of the field had yet appeared on the earth and no plant of the field had yet sprung up, for the LORD God had not sent rain on the earth and there was no man to work the ground, 6 but streams came up from the earth and watered the whole surface of the ground-- 7 the LORD God formed the man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being. (The KJV renders this soul, the NIV being, to note that what is formed is a person from the components)
We deserve death, but God gives eternal life as a giftconditional immortality
RO 2:5 But because of your stubbornness and your unrepentant heart, you are storing up wrath against yourself for the day of God's wrath, when his righteous judgment will be revealed. 6 God "will give to each person according to what he has done." 7 To those who by persistence in doing good seek glory, honor and immortality, he will give eternal life.
2TI 1:8 So do not be ashamed to testify about our Lord, or ashamed of me his prisoner. But join with me in suffering for the gospel, by the power of God, 9 who has saved us and called us to a holy life--not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time, 10 but it has now been revealed through the appearing of our Savior, Christ Jesus, who has destroyed death and has brought life and immortality to light through the gospel.
RO 6:19 I put this in human terms because you are weak in your natural selves. Just as you used to offer the parts of your body in slavery to impurity and to ever-increasing wickedness, so now offer them in slavery to righteousness leading to holiness. 20 When you were slaves to sin, you were free from the control of righteousness. 21 What benefit did you reap at that time from the things you are now ashamed of? Those things result in death! 22 But now that you have been set free from sin and have become slaves to God, the benefit you reap leads to holiness, and the result is eternal life. 23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
We do not receive immortality immediately, though we do have assurance of it. This happens at the second coming of Christ, at the resurrection. This is why the second coming is the hope of the New Testament Christians.
EPH 1:11 In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, 12 in order that we, who were the first to hope in Christ, might be for the praise of his glory. 13 And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit, 14 who is a deposit guaranteeing our inheritance until the redemption of those who are God's possession--to the praise of his glory.
2TI 4:1 In the presence of God and of Christ Jesus, who will judge the living and the dead, and in view of his appearing and his kingdom, I give you this charge: 2 Preach the Word; be prepared in season and out of season; correct, rebuke and encourage--with great patience and careful instruction. 3 For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. 4 They will turn their ears away from the truth and turn aside to myths. 5 But you, keep your head in all situations, endure hardship, do the work of an evangelist, discharge all the duties of your ministry. For I am already being poured out like a drink offering, and the time has come for my departure. 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.
1CO 15:20 But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep. 21 For since death came through a man, the resurrection of the dead comes also through a man. 22 For as in Adam all die, so in Christ all will be made alive. 23 But each in his own turn: Christ, the firstfruits; then, when he comes, those who belong to him. 24 Then the end will come, when he hands over the kingdom to God the Father after he has destroyed all dominion, authority and power. 25 For he must reign until he has put all his enemies under his feet. 26 The last enemy to be destroyed is death.
1CO 15:50 I declare to you, brothers, 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 theperishable 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."
1TH 4:13 Brothers, we do not want you to be ignorant about those who fall asleep, or to grieve like the rest of men, 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 own 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 each other with these words.
JN 5:24 "I tell you the truth, whoever hears my word and believes him who sent me has eternal life and will not be condemned; he has crossed over from death to life. 25 I tell you the truth, a time is coming and has now come when the dead will hear the voice of the Son of God and those who hear will live. 26 For as the Father has life in himself, so he has granted the Son to have life in himself. 27 And he has given him authority to judge because he is the Son of Man. Do not be amazed at this, for a time is coming when all who are in their graves will hear his voice 29 and come out--those who have done good will rise to live, and those who have done evil will rise to be condemned.
At the resurrection our bodies become like Christs body
1CO 15:42 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. 45 So it is written: "The first man Adam became a living being" ; the last Adam, a life-giving spirit. 46 The spiritual did not come first, but the natural, and after that the spiritual. 47 The first man was of the dust of the earth, the second man from heaven. 48 As was the earthly man, so are those who are of the earth; and as is the man from heaven, so also are those who are of heaven. 49 And just as we have borne the likeness of the earthly man, so shall we bear the likeness of the man from heaven.
JN 20:24 Now Thomas (called Didymus), one of the Twelve, was not with the disciples when Jesus came. 25 So the other disciples told him, "We have seen the Lord!" But he said to them, "Unless I see the nail marks in his hands and put my finger where the nails were, and put my hand into his side, I will not believe it." A week later his disciples were in the house again, and Thomas was with them. Though the doors were locked, Jesus came and stood among them and said, "Peace be with you!" 27 Then he said to Thomas, "Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe." Thomas said to him, "My Lord and my God!"
(This text describes Jesus post-resurrection body)..."
"Until the resurrection we are truly dead, we sleep in the dust (see above also)
JOB 14:12 so man lies down and does not rise; till the heavens are no more, men will not awake or be roused from their sleep
PS 7:4 if I have done evil to him who is at peace with me or without cause have robbed my foe-- then let my enemy pursue and overtake me; let him trample my life to the ground and make me sleep in the dust. Selah
PS 13:3 Look on me and answer, O LORD my God. Give light to my eyes, or I will sleep in death;
PS 90:5 You sweep men away in the sleep of death; they are like the new grass of the morning-- though in the morning it springs up new, by evening it is dry and withered...."
The dead do not ascend to heaven, (With the exception of Moses)
JUDE 1:8 In the very same way, these dreamers pollute their own bodies, reject authority and slander celestial beings. 9 But even the archangel Michael, when he was disputing with the devil about the body of Moses, did not dare to bring a slanderous accusation against him, but said, "The Lord rebuke you!"
(This text shows that Moses body was contended for, not just his soul. Moreover, it is clear that this was an unusual event, as there was a dispute over whether this could happen. At this point, Christ had not died yet for the sinner.)
AC 2:29 "Brothers, I can tell you confidently that the patriarch David died and was buried, and his tomb is here to this day. 30 But he was a prophet and knew that God had promised him on oath that he would place one of his descendants on his throne. 31 Seeing what was ahead, he spoke of the resurrection of the Christ, that he was not abandoned to the grave, nor did his body see decay. 32 God has raised this Jesus to life, and we are all witnesses of the fact. 33 Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear. 34 For David did not ascend to heaven, and yet he said,
" `The Lord said to my Lord: "Sit at my right hand 5 until I make your enemies
a footstool for your feet." '
JN 20:15 "Woman," he said, "why are you crying? Who is it you are looking for?" Thinking he was the gardener, she said, "Sir, if you have carried him away, tell me where you have put him, and I will get him." Jesus said to her, "Mary." She turned toward him and cried out in Aramaic, "Rabboni!" (which means Teacher). Jesus said, "Do not hold on to me, for I have not yet returned to the Father. Go instead to my brothers and tell them, `I am returning to my Father and your Father, to my God and your God.' "..."
