In The Collected Works of St. Teresa of Avila, there is this wonderful quote by St. Augustine:
"Give me, Lord, what You command, and command what You desire."
Where are we, in this prayer? We are there, sitting in humble silence, wanting nothing other than what God wants to give us. Wanting only what He desires and not seeking anything extra.
What purer form of humble prayer could one imagine?
Together with this should be our plea to God that He will put the desire on our hearts to seek only what He desires. Why? Because we know that God knows what is best for us. He knows what we really need at any given time. That is enough for us. That is all we need.
