A verb meaning 'to shut' or 'to lock out.' Used in Luke 13:25 in the parable of the closed door -- the master who shuts the door against latecomers who failed to enter while it was open.
Jesus's closed-door parable gives urgent eschatological warning: the door of grace has a closing time. The shock is not divine cruelty but human presumption -- many assume familiarity with Jesus without genuine relationship. 'Now is the day of salvation' (2 Corinthians 6:2). 'Behold, I stand at the door and knock' (Revelation 3:20).
