I have noted that many people acknowledge death and not eternal life. Sometimes I wake up from the middle of a nap and the first thing that washes over me is a fear of death. I imagine it being a never ending state where I am not awake but instead trapped and unable to move and think as I am doing so at this present time. How does one have hope in heaven and eternal life?
Faith, that whenever you die Jesus has you, you belong to Him, if you have trusted that He died for your sins and took your punishment in His body as a substitute for you, and was resurrected and sits on the right hand of the Father. If you trust that He has done these things and forgives you of your sins, He will take you to where He is, if you die, or if the end of the age comes and you personally get to witness Him coming in the clouds in power and great glory.
To be honest, based on thread title, I was thinking you were struggling with the same fear of heaven/new earth that I am, which is not fear of going to heaven, but rather fear of boredom, because the bible's descriptions of heaven is just a lot of singing (which I hate singing) and falling on our faces, with a lot of "there won't be this, and there won't be that" (things like marriage, oceans, nighttime, the sun and moon).
I know I'll go there but it's a little like going to visit a loved relative as a kid who lives somewhere where there's nothing else about that place you like, just them. You still really want to go see them, but you know at some point you're going to be bored because there's nothing to do at some point.
I still really want to see Jesus, but everything else sounds pretty boring.
I can't get through that.
But first you have to know that Jesus wants you to come see Him in the first place and that you really want to see Him.
