It is very easy to begin relying on our earthly blessings when we have them...and really hard to let them go if it comes to it. But if the Lord asks us to give something up (as He did the rich young ruler), it's always because He knows we are trusting in something that will not satisfy. He isn't trying to be cruel and take away the things we love. He's trying to give us the ability to completely trust in Him - the only thing that will never disappoint!

Everything in this life fades away. Hold it all loosely, and trust Him whether it is in the "giving or the taking away." (Job 1:21)
