i'm never sure in this parable, who's the treasure and who's the seeker? Do we find the kingdom of God, the Gospel of Jesus Christ and give up everything to possess it? Or did Jesus want us, "find" us and give up everything he had to possess us. As with many things in the Word, it's probably both.
We have to be found to find. Jesus did give up everything for us. And that's the Treasure we find! That when were hopeless, God gave up everything for us! How good is that!?
So what do we give up in return? Not to pay back. Could never be done. But to "find" more of him? "Do not be deceived: God is not to be mocked, for whatever a person sows, this he will also reap, because the one who sows to his own flesh will reap corruption from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit." Gal 6
There is a distinct tendency these days for us to buy that field and then never visit it again. Forget we even own the treasure at times. For believers to stop congregating. To just add Jesus to their lives and then go about as they would, maybe with a moral bent, but otherwise, indistinguishable from the culture. To slip out of prayer. To stop reading the Word. To find Bible Studies to be too much trouble. Instead of serving others, to feed our comfort and then wonder why we live sad, busy but unfulfilling lives. i'm not judging. i'm warning. We reap what we sow.
How do stop the process? Nevermind what Pete says, Seek the treasure! "If anyone serves me, he must follow me, and where I am, there my servant will be also. If anyone serves me, the Father will honor him." John 12
