Craig Groeschel said this quote
“ The simplest definition of prayer is communicating with God. That's it. Did you miss it? Let me say it again. Prayer is simply communicating with God. That one uncomplicated thought began to revolutionize my whole prayer life. What is communication? It's transferring a thought, feeling, emotion, or idea to another person. So prayer is giving God my thoughts, feelings, emotions, and ideas, by whatever means works. It doesn't have to be formal. It doesn't have to be long and dry. It's simply communicating. ”
