John 3:36: He that believeth on the Son hath life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
So you can see from this verse that God divides the world into two groups, he that believeth and he that believeth not. He that believeth has eternal life and he that believeth not does not have eternal life, but is condemned to hell. So every single person is either in one group or the other. What determines what group you are in is all based upon what you do with Jesus, whether you believe on him as your savior or whether you do not believe on him.
John 3:16-18: For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
17: For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18: He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
So in order to be in the group of unbelievers, all you have to do is nothing. If you have never put your faith in Jesus alone you are condemned already. We are all naturally condemned unbelievers until the moment we understand that we are a sinner in need of a savior and put our trust in what Jesus did for us on the cross and how he rose again to save us from our sin. That is when we go from the group of unbelievers and into the group of believers.
I John 5:12: He that hath the Son hath life; and he that hath not the Son of God hath not life.
In Matthew chapter 25 the bible again divides the world into two groups, sheep and goats. When Jesus comes back to judge the world the bible says he will separate the sheep from the goats, meaning the saved from the unsaved.
Matthew 25:31: When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:
32: And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:
33: And he shall set the sheep on his right hand, but the goats on the left.
34: Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
Matthew 25:41: Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels.
According to the above scriptures, the saved will inherit the kingdom of God prepared for believers in Christ and the unsaved will go into everlasting hell fire. So definitely you are going to spend eternity somewhere, which is what everlasting means, either in heaven or in hell. There are no other choices, only two places to go, one or the other.
So I hope if you have never put your trust in Christ alone to save your soul and are still in the group of condemned unbelievers, that you will put your trust in Jesus today and pass from death unto life.
John 5:24: Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
Once you put your trust in Jesus, you will be transferred from the group of unbelievers into the group of believers and receive the free gift of salvation.
Romans 6:23: For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Remember also that once you become a believer and pass from death unto life you will always be a believer because that is what eternal means, forever. You can never ever lose your salvation once you receive it. Making sure you are saved is more important than anything else in the world since your eternal destiny is at stake. It is easy to get saved, you only need to trust (or believe). To believe means to rely upon, and depend upon Jesus to save your soul, not just a mere consent that Jesus is the son of God, but actually trusting him as your own personal savior for the forgiveness of your own personal sins in order to get you to heaven. Your must have absolutely no trust at all in anything you do, like church, religions, good works, good life, repenting of sins, turning over a new life, etc. It is all Jesus;. Jesus paid it all. Jesus lived a perfect sinless life and all our sins were placed on him and paid for by him on the cross. He was our sin bearer so we could be forgiven.
I Peter 2:24: Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
To become a believer just call upon the name of the Lord and tell him that you admit you are a sinner and deserving of hell, but that you are now putting your trust in Jesus and him alone to save you and he will. God said thou SHALT be saved, not might be saved, but SHALT be saved. God said it and his word is true. It is impossible for God to lie.
Romans 10:9: That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Romans 10:13: For whosoever shall call upon the name of the Lord shall be saved.
