The Spirit of God will teach believers to pray for those things which honor God. He knows the mind of God. "Teach me, Lord."
1 Corinthians 2:11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
The Spirit of God will also make us more submissive to the Father.
When we get to the place where we want nothing but what God wants -- when His will becomes our will -- when we are willing to surrender all our plans, goals, wants and wishes to Him -- then we are ready to see God move in answer to our prayers.
