Lay no weight on the quantity of your prayers; that is to say, how long or how many they are. These things avail nothing with God, by whom prayers are not measured, but weighed.
True prayer is measured by weight, not by length. A single groan before God may have more fullness of prayer in it than a fine oration of great length.
The Secret Of Power In Prayer, Volume 34, Sermon #2002 - John 15:7
