The sermon titled "The Faithfulness of God" by Tommy Walls is a profound exploration of one of God's most foundational attributes—His unwavering faithfulness. Throughout the message, Wells emphasizes that God's faithfulness is integral to His nature and interwoven with all His other attributes, such as His wisdom, love, and justice. Walls begins by defining faithfulness as steadfastness, loyalty, and trustworthiness, traits that are perfectly embodied in God.

Walls challenges common misconceptions about God’s faithfulness, pointing out that God is not obligated to fulfill our personal desires but remains steadfast in fulfilling His own decrees and will. This distinction is crucial in understanding that God's faithfulness is aligned with His eternal purposes, not our immediate expectations.

Scripture is central to Walls' message, with passages like Lamentations 3:22-23 and Deuteronomy 7:9 underscoring God's enduring commitment to His word, creation, and covenants. He notes that the very fact we are alive and sustained each day is evidence of God’s ongoing faithfulness.

Walls also reflects on God’s faithfulness in the personal lives of believers, particularly in calling them to fellowship with Christ, guiding them through sanctification, and providing strength during temptations. Even when we falter, God's faithfulness remains unshaken, offering forgiveness and cleansing.

The sermon further explores the comforting truth that God’s faithfulness extends to our afflictions, using them as tools for our sanctification. Walls reminds the congregation that every trial and difficulty is allowed by God in His faithfulness to mold us more into the image of Christ.

As Walls concludes, he calls the congregation to respond to God's faithfulness with praise and a commitment to be faithful in return. The sermon serves as both a reassurance of God's unchanging nature and a call to emulate His faithfulness in our own lives, making it known to future generations.
