Where do we go when we die, do our consciousness exist in some other place?
28 Do not be afraid of those who kill the body but cannot kill the soul. Instead, fear the one who is able to destroy both soul and body in hell. Matthew 10:28, NET©
On the last day, God will judge everyone for their actions. Therefore, it is important that we fear God as the judge he is, because he has the power to send the sentenced souls to the final resting-place for sinners, eternally.
Deal with sin
In the gospel of Mark chapter 9 we are told what the consequences of sin is.
Wages of sin – Mark 9:43-49, NET©
43 If your hand causes you to sin, cut it off! It is better for you to enter into life crippled than to have two hands and go into hell, to the unquenchable fire.
45 If your foot causes you to sin, cut it off! It is better to enter life lame than to have two feet and be thrown into hell.
47 If your eye causes you to sin, tear it out! It is better to enter into the kingdom of God with one eye than to have two eyes and be thrown into hell,
48 where their worm never dies and the fire is never quenched.
49 Everyone will be salted with fire.
It is better to deal with sin in your life, instead of persevering in it. Get rid of everything that makes you stumble on the road.
Hell is a place where the holiness of God meets sin and sinners in its most refined form. Sin can not be in the presence of God. In the same way as fire burns when the circumstances are the right, with oxygen, fuel and heat. Likewise, a consuming fire arises when sin and the holiness of God comes in contact. Sin can not last in the presence of the holiness of God.
Hell is forever
Eternal lost – Revelation 20:13-15, NET©
13 The sea gave up the dead that were in it, and Death and Hades gave up the dead that were in them, and each one was judged according to his deeds.
14 Then Death and Hades were thrown into the lake of fire. This is the second death– the lake of fire.
15 If anyone’s name was not found written in the book of life, that person was thrown into the lake of fire.
The final repository is hell, and the hell will be thrown into the burning lake after the final judgment. Do whatever you can to avoid to get to this place.
