In the two events of God providing water from the rock, Moses obeyed God’s instructions the first time, but disobeyed the second time and wrested God’s word with severe consequences. This obedience and disobedience illustrate a dimension of understanding holiness and sanctification. God doesn’t want us to treat His words casually; His word is holy. If our ears are tuned to the holy, we will be running to the voice of the Sayer, obedient and trusting in His word.
