Here is a major turning point in Acts and in the history of the church. It is the conversion of Paul, which Luke repeats in his narrative for emphasis (see Acts 22:6-21; 26:12-18).

Paul never forgets what a zealous persecutor of the church he was (Philippians 3:6; 1 Timothy 1:15-16; 1 Corinthians 15:9). He had authority from the high priest in Jerusalem to arrest followers of the Way in the synagogues of Damascus and take them back to Jerusalem. His experience is much like that of Moses in Exodus 3:2:

• A light, a voice (Acts 9:3-4; Exodus 3:2-4).
• The solemn repetition of the name ″Saul, Saul″ (Acts 9:4) and ″Moses! Moses!″ (Exodus 3:4).

Notice Jesus asks Saul why the latter is persecuting Him (v. 4). Jesus takes persecution of the followers of the Way personally; to persecute them is to persecute Him (see Matthew 10:18-22). One of Saul's first lessons is on the solidarity of the believer and Christ. It is little wonder that the concept of being ″in Christ″ dominates his teaching. While Jesus questions Saul as to the reason for his zealous persecution, Saul is far more interested in who is addressing him (v. 5). Jesus identifies himself by His earthly name and address (v. 5; Acts 22:8) as the one who in reality is being persecuted by Saul. The Lord Jesus however has plans for Saul and tells him to go into Damascus and wait (v. 6).

Saul understands the Damascus road experience as his conversion, his seeing of the resurrected Christ (1 Corinthians 9:1; 15:8). The conversion of such a zealous persecutor as Saul provides further evidence for the truth and power of the gospel to save. No one could argue that Saul's seeing the resurrected Christ was wishful thinking on his part.

The zealous persecutor becomes the zealous apostle: ″Amazing grace, how sweet the sound that saves a wretch like me.″
