Prayer is talking and listening to God. It is sharing our thoughts, questions, fears, desires - opening our lives to God, holding nothing back. It is telling God our admiration for who He is, and contemplating His qualities. It is listening while He talks to us, providing comfort, peace, guidance, and direction requiring our worshipful obedience.
Prayer is also solidarity. Just as Jesus bore our burdens on His cross, we bear the burdens of others as if they were our own, laying them before the Father. In prayer, we approach Him in the names of those who don't yet know Jesus, asking God to bring them into His family.
Through special focuses, we unite in crying out to the Father, that His heavenly kingdom would break through on earth.
