Solomon hasn't said it because he didn't have the words, but he's reminded us of our need for God's grace. His unmerited and unearned favor over our lives. There is a riddle to life that will remain. Why do bad things happen to good people? I don't know because I'm not sure how we qualify "good." I know that I tend to fluctuate between self-righteousness and wickedness. Am I a good person? I'm not sure. But I am sure that I'm God's person, because He's covered me with His grace. I want to live for Him with the Holy Spirit's help, because He is good, and the eternal life I will spend with Him reminds me that life isn't limited to life under the sun. I trust Him to work all things for His glory and my good.
