The Ephesian 1:17-22 prayer will cause you to have a deep and intimate experience of Him.  Paul describes this kind of knowing in Philippians 3:10 (Amplified Classic):  "10 [For my determined purpose is] that I may know Him [that I may progressively become more deeply and intimately acquainted with Him, perceiving and recognizing and understanding the wonders of His Person more strongly and more clearly], and that I may in that same way come to know the power outflowing from His resurrection [[a]which it exerts over believers], and that I may so share His sufferings as to be continually transformed [in spirit into His likeness even] to His death,   The Ephesian prayer, prayed regularly will produce this type of deep intimate knowing of Him.
