We can learn a lot from King Solomon's life. He was the wisest king of his time and the Bible says he was rich and had everything he wanted. He built gardens, a great palace, and the temple for the Lord.
But he had issues and he drifted away from God. A good portion of Ecclesiastes is Solomon telling us about all the things he chased after, but he finds no fulfillment. The only true fulfillment we are going to find is in Christ.
