J.R. Miller emphasizes the profound impact of simple goodness in serving Christ, arguing that while eloquence and wealth may attract attention, it is the quiet influence of goodness that leaves a lasting impression on lives. He encourages those who feel inadequate or ungifted to recognize that even the smallest acts of kindness and a life of integrity can be a powerful ministry. Miller illustrates this through the life of an ordinary Christian woman whose humble goodness inspired her family and community over decades. He asserts that every believer can embody this simple goodness, which is essential in a world that often values showiness over sincerity. Ultimately, the sermon calls for Christians to cultivate a spirit of Christ-like goodness in their daily lives.
