"When you are happy, so happy that you have no sense of needing Him (God), you are tempted to feel His claims upon you as an interruption," - C.S. Lewis "A Grief Observed".
I've found in my own life that the times when I seek God the most are the times when life is hard. When things are going easily, it is so easy to lose diligence and focus. But, when disaster strikes, it is those times that we seek God the most.
In Jeremiah 37, it says that "neither he (Zedikiah) nor his servants...listened to the words of the Lord." But when the Chaledeans had surrounded and beseiged Jerusalem, verse 3 says "King Zedikiah sent Jehucal... to Jeremiah the prophet saying, 'Please pray for us to the Lord your God.'"
Now there is absolutely nothing wrong with crying out to God when things go wrong. I just believe that all of us, myself included, should work harder at seeking after the Lord when times are easy.
"Seek the Lord and His strength, seek His presence continually." - 1 Chronicles 16:11
