2 Chronicles 7:14
“if My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land.
The word picture for pray is: "to speak the tongue of tongues".
Here we are reminded that one of the most powerful forms of prayer is to speak what has already been spoken by God.
You need never be lost for words to pray, the Scriptures are literally the prayer book of the ages.
"Thy Kingdom come, Thy will be done on earth as it is in Heaven".
