He strongly emphasized signs and wonders, which he referred to as "Doin' the Stuff", the priesthood of every believer and that every Christian has the ability to prophesy and heal the sick. While this is not a new concept, Wimber was a key figure in the introduction of the concept that praying for the sick (or anything else) shouldn't be saved for special healing services, but should take place at every Church service, and out on the streets (by every believer). As a result, many churches have prayer time after the sermon. The Vineyard worship style has also had a wide influence on the church.
