According to the Bible, when we die we corrupt into dust and cease to exist.
Genesis 3:19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
In death there is no consciousness
Ecclesiastes 9:5 For the living know that they shall die: but the dead know not any thing…
We do not possess an immortal soul – we are a soul
Genesis 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
When we die our soul dies.
Ezekiel 18:20 The soul that sinneth, it shall die...
When we are placed in the grave our soul is placed in the grave
Psalms 89:48 What man is he that liveth, and shall not see death? shall he deliver his soul from the hand of the grave?
The unconsciousness of death is likened to sleep.
1 Kings 2:10 So David slept with his fathers, and was buried in the city of David.
Acts 7:60 And he (Stephen) kneeled down, and cried with a loud voice, Lord, lay not this sin to their charge. And when he had said this, he fell asleep.
Our only hope of life after death is that of resurrection from the dead.
Acts 24:15 And have hope toward God, which they themselves also allow, that there shall be a resurrection of the dead, both of the just and unjust.
Philippians 3:11 If by any means I might attain unto the resurrection of the dead.
This is promised to those who believe and obey the gospel preached by Jesus Christ and his apostles.
When they die, those who believe and obey the gospel are said to sleep in Jesus awaiting resurrection when he returns
1 Thessalonians 4:13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. 14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. 16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words.
We meet the Lord in the air when he comes to establish the kingdom of God on earth and reign with him over the mortal population of the earth for 1000 years.
Revelation 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
