Though under attack from within and without, Christ will build His church. Summaries have marked pivotal points in Luke’s discourse. The first (2:42-47) glimpsed the vitals of the newborn church. The second (4:32-35) its witness within. Now, the third summary considers her witness without, that is with an eye to the outside. The holy presence and power of God is central in the main thought of the passage. And the witness and testimony to the gospel of the Lord Jesus Christ is its purpose. In typical fashion, signs are mentioned to be followed by a sermon. It all points to Christ, here in the church’s witness without.
