But they had heard only, That he which persecuted us in times past now preacheth the faith which once he destroyed.
Note 2 at Ga 1:23: In the Greek text, this word "heard" means "they kept constantly hearing" ("Galatians in the Greek New Testament" by Kenneth S. Wuest, p. 55). In Ga 1:24, the Greek verb translated "glorified" is used in the same way. It denotes continuous action. So, these verses are saying that the testimony of Paul's conversion from persecutor to preacher was consistently being told among the Christians and was constantly causing the saints to glorify God. We can only speculate about how much encouragement this brought to the saints, but there is no doubt that Paul became a trophy of God's grace (1Ti 1:16).
