J.R. Miller emphasizes the profound significance of our hands in his sermon 'Hands: A Study,' illustrating how they are instruments of power, creativity, and service. He reflects on the journey of a hand from infancy to old age, highlighting the potential for both good and harm that resides within our actions. Miller urges the congregation to train their hands for diligent work, loyalty to duty, and gentle ministries, drawing parallels to the hands of Christ, which bear the marks of sacrifice and love. He concludes by reminding us that even in stillness, folded hands can be powerful through prayer and intercession, leaving a lasting impact on the lives of others. Ultimately, the beauty of our hands is measured not by their appearance but by their willingness to serve and bless others.
