Prayer is typically viewed as being a time of silent "talking" to God. Sometimes we're not too silent.
We praise and adore God in prayer. We recognize Who He is and what He does. We seek His guidance and provision in our lives. We ask Him to intercede in the lives of friends, relatives and loved ones. In prayer we confess our sins. Those are what I would call the "quiet" part of prayer. We may even sing and worship but that is still relatively silent.
But then there's the "active" part of prayer. Throughout this study, we have sought to transform or reform our lives into lives of prayer. A life of prayer is when we are "being" with God throughout the entire day. We are thinking about Him and speaking to Him. We may sing to our Father during the day, but He's looking for more from us.
