The Bible tells us that, "it is appointed for men to die once, but after this the judgment." (Hebrews 9:27) This means we all have that appointment - Death is a certainty. The statistics are unchangeable; 100 out of every 100 have died....which makes some people fearful of death because of the unknown - their eternal location.
The child of God knows what to expect at life's end. At our physical death, we will be changed. Our physical body will die and decay into dust because we live in corruptible bodies - but, as the apostle Paul wrote, "This corruption must put on in-corruption, and this mortal must put on immortality." (1 Cor. 15:51) We will be changed! As the bible says, "it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him." (1 John 3:2)
Jesus said, "In my house are many mansions. I go to prepare a place for you, that where I am, there you may be also." (John 14:2-3) Here Jesus is telling the believer that they will enter into the eternal existence with God.
For the the carnal man death is just as certain but, the location of eternity is different. The Bible says this concerning the unbeliever, "The angels will come forth, and separate the wicked from among the just, and cast them into the furnace of fire. There will be wailing and gnashing of teeth." (Matthew 13:49-50) Yikes! Hell is a real place and is reserved for the unbeliever. Revelation 20:15 says, "And anyone not found written in the Book of Life, will be cast into the lake of fire."
There is no escaping death nor the events that will follow for your soul. The only question is, Where will your soul spend eternity?
The Truth
"He that believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him." (John 3:36)
