This verse surprised me in my Bible reading this morning.
Proverbs 21:31 (The Message) Do your best, prepare for the worst — then trust God to bring victory.
I have been reading The Message, which is a paraphrase. My hope is to get a fresh perspective on verses I have read over and over. This would be a good example. Here is the verse in a couple other translations:
NIV - The horse is made ready for the day of battle, but victory rests with the LORD.
KJV - The horse is prepared against the day of battle: but safety is of the LORD.
In The Message, we lose the horse, but retain the idea of preparation. Of course, preparation for battle would include doing your best. If you didn't do your best, you'd surely die. Sometimes you die anyway. But that brings on the second part. Victory is in the Lord's control.
OK, time for lessons! You'll have to draw your own parallels to home education. :-)
