The man in the parable (Matthew 13:44) "went in his joy" to sell everything. Why? Because he found a treasure worth possessing above all else he had. He did not, however, have enough to buy the treasure. Fortunately, he only needed enough to buy the field. In a similar fashion, God offers his kingdom of righteousness, peace, and joy (Romans 14:17) as incomparable treasure at a price we can afford! We can't pay the full price for the life which God gives us; but when we exchange our life for the life which God offers, we receive a treasure beyond compare.
