When things go wrong we always want to find someone to blame. It makes things easier to handle when we can shame a guilty party. When we sin there are consequences. It was a common thought in Jesus day that if someone was sick it was because they sinned or someone like their parents sinned. Look at Job- everyone believed that what he was going through was his fault.
In John 9 the disciples asked Jesus whose fault it was that a man was blind. What sin did he do that caused this? It sure made it easier to disregard the suffering because after all, it was their own fault. They brought it on themselves.
But Jesus (as He does) brought a new line of thinking. Maybe there is suffering so God can be glorified. There was a cause and a purpose that was bigger than the person in the middle of it all. This can be really helpful when your overwhelmed and can’t seem to get to the end of the crap in your life.
Don’t get me wrong here- a lot of suffering we bring on ourselves! It’s just that it’s not always the case. The first thing to do is check your heart and see if you need to make adjustments but also understand that not all things are about you.
How would we know good if we didn’t know evil? How could we choose God if we didn’t have any other option? God didn’t make robots, He made humans. He gave us free-will. We can chose to sin and suffer the consequences. We can chose to not sin and sometimes still have horrible things happen, but it gives us the most amazing opportunity to know a God who loves and can AND DOES redeem. There are bigger purposes if your willing to step outside yourself.
