Great words from Andrew Murray about working with the Holy Spirit in our prayer time. Let the Holy Spirit be our prayer helper and teacher.

You complain that you do not feel able to pray thus, and ask how you may be fitted to do so.  You speak much of the feebleness of your faith in God, and love to souls, and delight in prayer.  The man who is to have power in intercession must cease these complaints.  He must know that he has A NATURE PERFECTLY ADAPTED TO THE WORK.  An apple tree is only expected to bear apples, because it has the apple nature within it.  “You are God’s workmanship, created in Christ Jesus unto good works.”  The eye was created so see:  how beautifully fitted it is for its work!  You are created in Christ to pray.  It is your very nature as a child of God.  The Spirit has been sent into your heart—what to do?  To cry Abba Father, to you draw your heart up in child-like prayer.  The Holy Spirit prays in us with groanings that cannot be uttered, with a divine power which our mind and feelings cannot understand.  Learn, if you would be an intercessor, to give the Holy Spirit much greater honors than is generally done.  Believe that He is praying within you, and be strong and of good courage.  As you pray, be still before God to believe and to yield to this wonderful power of prayer within you.

These are quotes from The Inner Chamber by Andrew Murray on Moses the man of prayer.
