As Moses reaches the end of his life in Deuteronomy 31, his final words become a charge to Joshua and a reminder of the power of words. Moses speaks “be strong and courageous” three times, and God later repeats those same words three more times to Joshua. The lesson is clear: words can guide, strengthen, and set a heart on fire. What we speak into the lives of others can become the very words God uses to sustain them in their future battles.
