Final answer:
Saul first encountered the Lord on the road to Damascus, where he was blinded by a light and then led to Judas' house on Straight Street, where he was healed and gained his sight back.
Step-by-step explanation:
Saul, also known as Paul after his conversion to Christianity, encountered the Lord for the first time on the road to Damascus.
This event is detailed in the Acts of the Apostles (Acts 9:1-2; 9:5–6) in the New Testament. According to scripture, Saul was struck by a blinding light and heard the voice of Jesus. Consequently, he was led to the home of a Jew named Judas on Straight Street in Damascus.
It was there that Ananias, following a vision, healed Saul by touching him, causing "scales" to fall from Saul's eyes, and restoring his sight.
