Life throws you curves and stresses and large piles of poo in this fallen world, and yet we are called to be content. Paul tells in Philippians that he has learned to be content in all situations and circumstances. He said, "I can do all things through Christ who gives me strength." It's probably one of verses of the Bible that's taken out of context the most.
It doesn't mean that I can jump off a cliff and fly or disappear or have x-ray vision because Christ gives me strength. Rather, in context, it means that because we have the strength of Christ, we are able and equipped to deal with whatever life throws us.
I'm trying my best to rely on Christ today. My day has sucked, sucked, sucked so far. Stresses are piling up. I know Jesus will help me through it all. I trust that He is both sovereign and good. But that doesn't make it any easier to be content in the midst of madness that is not necessarily of my making!
However, it was pointed out to me by someone quite wise that Paul tells us that he has LEARNED to be content in all things. It is something that must be practiced and prayed over, not something that is easily attained. Paul was a SAINT, after all. But then again, so am I (small "s")... So here I go...
