What can we learn from Moses striking the rock twice?

Moses' act of striking the rock twice serves as a profound lesson about the finality of Christ’s sacrifice. This second striking was absolute disobedience and misrepresented the work of Christ, suggesting that His sacrificial death needed to be repeated. Hebrews 10:10 clarifies that we have been sanctified through the offering of Christ once for all. Thus, Moses’ failure to obey God's command to only speak to the rock signifies a misunderstanding of grace and the completeness of Christ's work. This teaches us the importance of recognizing the sufficiency of Christ's singular sacrifice for our salvation.
