In the third petition we are taught by our Lord to glorify and bless Him with submission to His providence and obedience to His commands.--That is we can enjoy Him and Be very happy obeying Him since we were at one time enemies and haters of His commandments.--Now, His mercy is seen in this, that, we never offer up total or complete obedience- only gospel obedience made acceptable because of Christ.--That our God would stir in us a holy zeal, passion, faithfulness, constancy as the angel enjoy in heaven.
