The story of Bartimaeus is a good illustration of how that works in our lives. He needed, first of all, to call out God. That happens through prayer. We open up the lines of communication between us and God. We make ourselves heard, not only when we come to church on Sunday, but daily as we offer up prayers of intercession and thanksgiving.
Prayer can happen any time during the day.
That prayer of Bartimaeus is a powerful one. It can become part of the rhythm of our lives. As it becomes part of our pattern of living, we will find times to set apart. They will become times of refreshment and renewal in our lives. Many things keep us from opening our lives to God.
