The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light.
The night (of evil) is far spent, the day (of consummated triumph over it) is at hand: let us therefore cast off (as a worn-out dress) the works of darkness - all works holding of the kingdom and period of darkness, with which, as followers of the risen Saviour, our connection has been dissolved,
And let us put on the armour of light - the armour which befits "the children of the light," described at large in Ephesians 6:11-18: see also 1 Thessalonians 5:8.
