When I was preaching through the book of Ephesians I came across a series of transcribed lectures that Eric Alexander had delivered at the 1984 Urbana Conference on the first three chapters of the Epistle. Recently I have found a series he did at the 1981 Urbana Conference on Acts 2, 4-6, 6-7, 13:1-6 and 16. I am certain that you will benefit immensely from reading them. The link to each exposition is listed below:
Eric Alexander on Acts
Pentecost and Missions (Acts 2)
Mission and Opposition (Acts 4-6)
Mission and the People God Calls (Acts 6-7)
Mission and Vision (Acts 13:1-6; and 16 )
Eric Alexander on Ephesians
The Basis of Christian Salvation (Ephesians 1:1-14)
The Ministry of Christian Interceding (Ephesians 1:15-23)
The Nature of Christian Experience (Ephesians 2)
The Privileges of Christian Ministry (Ephesians 3)
