Man’s future reward is not in heaven..
The heaven, even the heavens, are the LORD’S: but the earth hath he given to the children of men.
And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand, Until I make thy foes thy footstool.
But the meek shall inherit the earth; and shall delight themselves in the abundance of peace.
