There's a saying I originally heard from Mark Batterson at the National Community Church.
Work like it depends on you. Pray like it depends on God!
This really resonates with me. Some people really decide to think, "hey, God put me in this place and he'll help get me out of it" then proceed to do nothing waiting for God to help out. A life of apathy ensues.
Then there are others who are so convinced that they have to do things right and that everything rests on their shoulders. Without them everything would crumble. A life of control and narcissism follows.
Sadly, I fall into both of these categories more than I'd like to admit. Truly I probably fall more into the bucket where I rely more on myself then on others or God.
Balancing work and prayer together is key. For me though it's the need to constantly remember that any given moment absolutely everything could fall apart. It's only through faith in God and that all the millions of tiny things will go on correctly that we know our world will stay together.
Work like it depends on you. Pray like it depends on God.
