Acts 4:33

With great power. The witness of the apostles was presented, not in their own strength, but in a power they could never have engendered within themselves. Theirs was the energizing of the Divine Spirit.

Gave. Gr. apodidomi, “to deliver [that which is due].” The form of the verb used here may be understood to mean that the apostles “continued to deliver” the witness they had already given on Pentecost and in the Temple. The apostles felt themselves under an inner compulsion to bear witness. They had seen the wonderful works of Jesus. They had seen Him die. They had seen what they had not believed could happen — the Lord had risen from the dead. This crowning miracle constituted the climactic point of the apostolic preaching. The apostles could tell the story as eyewitnesses to a resurrected Lord, and tell it they did “with great power.”

Grace. Gr. charis (see on Rom. 3:24). Charis here may be taken in the sense of “favor” (as in Luke 2:52), and so indicate that the favor of the people toward the Christians still continued. However, in view of the context, which emphasizes the spiritual gift of power that they received, it is probably better to understand charis in its more technical sense of divine grace (as in Luke 2:40).
