Today, there is a new emphasis on the length of prayer instead of the best type of prayer. Jesus never recommended long prayers, and there are only a few instances where Jesus prayed long prayers. This is not to say that communion with God is not important. It certainly is, but formal prayer is only one part of our communion with the Lord.
Psalm 5:1-2 uses the words "prayer" and "meditation" interchangeably. Communing with God through keeping our mind stayed on the things of the Lord is also prayer. There are also times in prayer when we need to be still and know that God is God (Psalm 46:10).
Many times we ask the Lord to speak to us, but He can't get a word in because we're doing all the talking.
