I will do my best to cut to the chase. I can write a million words for this topic but this should be something you might actually read.
Some people have a great fear of death, why? Some people have a great fear of living. It's unpredictable and it's unclear.
Some people do not fear death but, pain, why? Death is one thing but pain is another.
If you believe in a heaven of such a place, why? Because I want to be where God is.
what makes you so sure your view is the correct one?
These questions have no answers. Believing in Heaven is believing in God. Why?
Because If I choose to follow God, and He isn't real, I have lived my life as a lie and felt loved by something that didn't exist, but if choose to decline that love, and Jesus Christ did die on the cross for my sins, then I not only took the death of God's son for granted but lost everything in the process and will forever sit in the guilt of betraying Him. The question is what is the bigger risk. If I choose God and he isn't real, I lost nothing, but If I refuse Him, and he is real, I lose everything.
That's why I choose God. Because I am afraid of death and death isn't your body dying off, it's the guilt of betraying God's love.
That's my answer.
