God raised us up with Christ [See Col. 2:12] and seated us with Him in the heavenly realms [i.e., in the church. See 1:3] in [fellowship with] Christ Jesus.

So, it says, "You who are asleep, wake up and rise from the dead, and Christ will shine on you [i.e., illuminate you]." [Note: The foregoing words may have been an early saying, used at someone's immersion, which included the ideas of "rising up" (See Col. 2:12) and "illumination" (See Heb. 6:4)].
