Why do we have to wait to...?

Well if you are speaking of the heaven as in spiritual world

Mentioned in the Bible, it states in said Bible that a man(human being) can enter heaven only thru death And belief in son of God.

Philosophically thinking, most like because the spirit is too heavy when encumbered by the live body

Why do we have to wait to go to heaven?

~~~ You don't!

Why cant we have heaven before death and after?

~~~ We can, and do!

Jesus said; "Heaven is at hand!"

That means right Here! Right Now!

If you are not Here! Now!, you never will be!

you do have heaven before death. its what you do in the midst of all the people that decides what and who you are. the happiness that you spread amongst the people is your happiness. your happiness is what heaven is. after death, it is what you do that gives you heaven. if you have lived a happy life, making all others around you happy, then heaven here and after death are guaranteed.

It sounds like this is a question asking 'why do we suffer' In a different way. Some suffering can be pinned on other humans, taking the form of evil, but not all. I do not believe that there is an answer, or at least one we can comprehend. Prehaps it is so that we can reach out to others?

Live long life to make your life worthy of going to the state of heaven. Be patient.

The MAP. You do not have to wait at all. Nobody is waiting. They are just lost and do not know the way. The Bible is THE Map to what is ours to claim. Only the honest-hearted; true hearted ones are finding the way from the Bible. Read Psalm 119:105. Let it light your way now.

Why can't we overcome this idea of paradise after death?

How selfish is it to concern ourselves with our own salvation, when we could be helping others?

We should make the world our paradise for all to enjoy.

You do. Earth isn't our home. The afterlife is. We're only here for a short amount of time, and when our body dies, we go home. You were there before you came here, and you'll go back there when you die.
