By making Ezekiel as unyielding and hardened as the people he is sent to, God is ensuring that Ezekiel will not be easily discouraged or swayed by their resistance. This divine fortification is crucial for Ezekiel's success in delivering God's messages, as it allows him to remain steadfast and committed in the face of adversity.
The verse underscores the idea that God provides His servants with the necessary strength and resilience to carry out their divine missions. It serves as a reminder that when faced with difficult tasks or opposition, believers can rely on God's support to remain firm and unwavering. This assurance of divine empowerment is a source of comfort and encouragement, emphasizing that God equips His followers with the inner strength needed to overcome obstacles and fulfill their purpose.
