Mediocrity for Anyone?

Jesus ministry was wonderful. Thousands of people were healed and many people chose to follow him. Jesus said that it was better for him to go away, so that the Holy Spirit could come in his place.

Jesus promised his disciples that they would do greater things than he did, when the Spirit came. This promise seemed to be fulfilled in the book of Acts, but this move of the Spirit did not last long. For most of the last 2000 years, the church has generally experienced mediocrity.

Jesus promise was not true, so why are we satisfied with mediocrity.
