You, Oh Lord, Know the Hearts of All

The sermon centers on the divine sovereignty and intimate knowledge of God's heart, illustrated through the selection of Matthias to replace Judas, emphasizing that only God can discern true faith and calling. It highlights Peter's transformation from a flawed, impulsive disciple to a leader shaped by Christ's patient preparation, demonstrating that spiritual leadership is not about human merit but divine work in the heart. The contrast with Judas—externally involved in miracles and ministry yet inwardly unrepentant—serves as a sobering warning that outward actions do not guarantee salvation, and that true conversion requires a surrendered heart. The passage underscores the necessity of prayer, unity, and reliance on God's wisdom in discerning His will, especially when human judgment is blind to the heart's true condition. Ultimately, the message calls believers to examine their own hearts, repent where needed, and trust in God's faithfulness to complete the work He has begun.
