It does not matter what happens to our body after we die. I know that when I die, my soul will immediately go home to Jesus Christ my Lord and Savior in heaven, and I will be with Him throughout all eternity. He has promised this to all his saints (all believers and followers of Jesus)
God created our souls to be eternal, therefore we will either live eternally in heaven with God, or in "the hot place", as one of my pastors used to say. And some people think if they were "a good person", they will go to heaven...but it isn't like that. It is the relationship with Jesus Christ our Lord that matters, not what we do and it isn't about organized religion either.
"He who has the Son has life; he who does not have the Son of God, does not have life." (meaning does not have eternal life with God in heaven)
"For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life." (in heaven)
John 3:16 (N King James Bible)
Everlasting life is what every soul will have,and if you know Jesus, you will spend eternity in heaven with Him. Here is another scripture:
Jesus said to him,
"I am the Way, the Truth and the Life. No one comes to the Father except through Me." John 14:6(New King James Bible) (Jesus was saying that unless you know Him, you cannot have eternal life in heaven)
