Moses faced harsh criticism from his own siblings Miriam and Aaron, who questioned his authority and marriage choices. When they publicly challenged his leadership, God defended Moses with powerful words: He is faithful in all my house. This divine endorsement reveals what God values most - trustworthy, dependable character that remains loyal through decades of difficulty. Moses demonstrated faithfulness for forty years through incredible challenges including family problems, leading millions through the wilderness, managing constant complaints, and facing his own failures. Faithfulness means being a reliable steward of everything God has entrusted to us - our families, work, resources, and opportunities. The principle is clear: if you are faithful with little, you will be faithful with more.
