In "Biblical Perspective" Gayle Woods writes:
Miracles tend to produce excitement, but not necessarily faith. The disciples had seen many miracles, but they were still having issues with their faith. The people were excited about physical healings and paranormal dis- plays of power, but not many were coming to Jesus for spiritual healing. Today some have an unnatural hunger for the supernatural display of miracles in the physical realm, not realizing that the results are temporary and earthly at best. Our mission is spiritual in nature rather than physical.
