It begins with such a profound statement:
"O God, You make the minds of the faithful to be of one will."
First thing that confesses is that IF the people of God truly have one will, it's not their doing, but God's. He is the One is causes His people many minds to become a single mind.
Second, what is this one will? Is it not this: THY will be done!? If there is one thing that God's people desire it is for His gracious, perfect and holy will to be done; not their wills, not their plans, not their hopes and schemes and ambitions, but solely God's good and gracious will: that people might be freed from their idolatry and look to Christ and Him alone for every good gift and know Him as their loving Savior by the Spirit's power.
How we need this prayer! And so we ask:
"Grant that we may love what You have commanded and desire what You promise."
