Remains in play. This spell can be cast on a friendly unit which is anywhere on the battlefield, even if it is engaged in close combat. If successfully cast, all models that are in the unit get a bonus of +1 to all their rolls to hit (both shooting and close combat attacks). Once it is cast, the Blessing remains in play until it is dispelled, or until the Wizard chooses to end it (which he can do at any time), attempts to cast another spell or is slain.
