The Greek noun anablepsis means "recovery of sight" or "looking up again." It is used once in the New Testament — in Luke 4:18 where Jesus reads from Isaiah 61 and announces His mission to proclaim "recovery of sight for the blind."
The single occurrence of anablepsis in Luke 4:18 is one of the most programmatic statements of Jesus' ministry. This is both physical (Jesus literally healed the blind) and spiritual (He opens the eyes of those blinded by sin). The Christian ministry continues this mission: proclaiming the gospel is giving sight to those who cannot see God.
