Isaiah 30:15-21 - God clearly says Read the Bible, Be devoted to Prayer, Be alert, and continue to do what we now, BUT God also says, “Listen to the Immediate and Direct guidance of the Holy Spirit.” Take note of the words Immediate and Direct! As we embrace all the disciplines and resources of God, we also must not neglect the Holy Spirit as revealed in Isaiah 30:21. NT revelation give us much more insight about the work of the Holy Spirit which is necessary for our Rest, quietness, Trust, and Strength.
