[26:18] 1 sn To open their eyes so that they turn… Here is Luke’s most comprehensive report of Paul’s divine calling. His role was to call humanity to change their position before God and experience God’s forgiveness as a part of God’s family. The image of turning is a key one in the NT: Luke 1:79; Rom 2:19; 13:12; 2 Cor 4:6; 6:14; Eph 5:8; Col 1:12; 1 Thess 5:5. See also Luke 1:77-79; 3:3; 24:47.
