Rest: let's strive diligently to enter it.

Hebrew 4:11 Let us, therefore, make every effort to enter that rest, so that no one will fall by following their example of disobedience.

If there's anything to strive for, it is to be rested. Lest you 'fall by following their example of disobedience'. I find this greatly oxymoronic (I don't even know if this sentence makes sense!). On one hand we have to strive diligently, on the other we have to rest. How la? 

The rest that Hebrews is referring to here is the finished work of Jesus. And it is asking us who believe, so that those (hebrews 4:10) who enters God’s rest also rests from his own work, just as God did from his. 

So whenever we embark on anything, start from the posture of rest, knowing that God has done it for you. Start from the position of completion, believing that He has given you success. 

And this is rest: believing in Jesus and His finished work.
