What's yours? What do you call your own? Think about your body, your life, your ambitions and desires, your family, your wealth (or lack thereof), your job, education, past achievements and awards, etc., etc. What of all that actually belongs to you? How you answer that is going to say a lot about your relationship with...well, you know WHO! If I claim anything as being mine, then I'm not where I need to be with God. All that I am, and all that I call "my own" belongs to Him! And if you really think about that, it's one of the most liberating thoughts a person can have!! If I know its not mine, and more importantly, if I know I've given all this to the Lord, then I know He owns everything. Not me! And if He takes what is His, well, it was His to take. If I grasp onto something and He takes it, I think I've been robbed! But if I have given ownership of all that I have to Him, then I accept that He can do whatever He wishes to do with what is His!
A great illustration I heard years ago was the account of a wealthy agricultural icon from the Midwest. He was told that his entire crop of wheat had been lost to a locust invasion. A preacher happened to be visiting with this man and asked him how was he going to handle this. His answer was beautiful! "If God wants to feed His locusts with His wheat, then that's His business! The wheat was His, the locusts are His, and so am I. If He can feed His locusts, why should I think He won't take care of me?!"
The best thing you can do with what you call "your own" is to surrender it all to God! You'll have peace and He will know that nothing comes between you and Him.
