She grew up believing she knew it all, but realized that, in the end, she leaned quite heavily on God to rescue her. The events chronicled in this story collection taught author Martha Roberts to laugh at herself and not take life too seriously. I Knew It All is a gift of laughter for those readers who might be feeling down because of life's difficulties, war, COVID, etc. She points out that God's Word says, "Laughter doeth good like a medicine." The author hopes readers learn "Don't sweat the small stuff," and laughter helps us get through the rough times. The author says, "If you laugh at a person slipping and falling on a banana peel you will laugh with me as you read the book because I laughed as I wrote it."
