For His Kingdom

If Apostles and Prophets are absent from church leadership then you get a church that is built on a dysfunctional Earth-to-Heaven model.
Heaven’s design for leadership is based on a team of diverse anointings that work together in a Culture of Honour to release Heaven on Earth. Without such giftings present in a church, it's simply a group of nice people, but certainly it's not operating as Church!
The Biblical model has these priorities:
Apostles (Heaven: see Eph 2:6-7, Col 3:1-2)
Prophets (Spirit world, what is God saying)
Teachers (Articulating the Kingdom) and
Workers of Miracles (The supernatural activity of the believers).
