Numbers 20:10-12
“Moses and Aaron gathered the assembly together before the rock, and he said to them, “Listen now, you rebels! Shall we bring you water out of this rock?” Moses lifted up his hand, and struck the rock with his rod twice; and water came forth abundantly, and the congregation and their livestock drank. Yahweh said to Moses and Aaron, “Because you didn’t believe me, to sanctify me in the eyes of the children of Israel, therefore you shall not bring this assembly into the land which I have given them.””
This passage recounts an incident during Israel's forty years in the wilderness. The people are complaining about lack of water, a recurring theme. Moses, frustrated, strikes a rock instead of speaking to it as God commanded, and for this act of disobedience, he and Aaron are forbidden from entering the promised land.
What does it mean to trust God's instructions even when facing immense pressure and frustration?
