I believe Jesus didn't reveal much about heaven because he wants it to be a wondrous surprise for his bride. I know that if he had told us more about heaven, we would be thinking too much about life there rather than pursuing the kingdom here.
Let us be ready. Let us prepare ourselves. We have work to do.
"And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband."
