Why did Jesus send Ananias to Saul in Acts 9?

Jesus sent Ananias to Saul so that Saul might receive his sight and be filled with the Holy Spirit. The Lord also declared Saul a chosen vessel to bear His name before Gentiles, kings, and the children of Israel, marking a major turning point in Acts.

Les explains that Ananias was afraid of Saul because of his reputation for persecuting Jewish believers, but the Lord told him to go anyway. In verse 15 the Lord called Saul a chosen vessel to bear His name before Gentiles, kings, and the children of Israel, which Les identifies as the big turning point in the Book of Acts. Ananias went to the house of Judas, laid hands on Saul, and said the Lord Jesus had sent him so Saul might receive his sight and be filled with the Holy Spirit. The scales fell from his eyes, he received sight, arose, and was baptized. Later Saul preached Christ to Jews in the synagogue, not yet to Gentiles.

Acts 9:17

And Ananias went his way, and entered into the house; and putting his hands on him said, Brother Saul, the Lord, even Jesus, that appeared unto thee in the way as thou camest, hath sent me, that thou mightest receive thy sight, and be filled with the Holy Ghost.
