"Again, the kingdom of heaven is like unto treasure hid in a field; the which when a man hath found, he hideth, and for joy thereof goeth and selleth all that he hath, and buyeth that field."
I think this is a great scripture... just pointing out how cool heaven is. Joseph Smith said that if men could see just the glory of the Telestial Kingdom, the lowest possibility we have of an afterlife... that they would be killing themselves to get there. Perhaps when we have those moments where we realize how far below God we are... we can remember that Earth life is so far below Heaven in that same way... and the peace and rest and fulfillment that we seek and can never quite find... we WILL find, because that is our home, and the fulfillment of all the positive things that the heart can conceive.
Maybe another thing to ask ourselves is, do we see heaven and God's kingdom as the precious thing that it is? Do we realize its value? Are we walking away from a treasure that is greater than everything we have now? I think of Job, who lost everything... and then gained more than he had in the first place. I don't think that God blesses all of us exactly the same way... but when we sacrifice *anything* for God, we receive b'zillions of times more than we ever sacrificed... every time. Emotionally, spiritually... materially... whatever it is, God doesn't fail. Like Job, he teaches us patience sometimes... but he always comes through after building our faith a little. :)
