The bible mentions something about "eternal life" what does it refer too?
According to the bible, everyone have eternal life. The only difference is whether is it in hell or in heaven. So whenever u read, "believes and gain eternal life", it may just means eternal life in hell... hehehe...
Now this is eternal life: that they may know you, the only true God, and Jesus Christ, whom you have sent. (John 17:3)
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. (Romans 6:23)
The life appeared; we have seen it and testify to it, and we proclaim to you the eternal life, which was with the Father and has appeared to us. (1 John 1:2)
