JMNT(i)
8 For it follows, both if we are (or: should be) living, in the Lord (or: for, to and by the Lord [= Yahweh or Christ]) we are (or: could and should be) living, and then, if we may (or: would) be dying, in, for, to and by the Lord we would be dying. Then, both if we are living, and if we may be dying, we are the Lord's (we constantly exist being of [Yahweh]; we continuously belong to the Lord; we are from the Owner).
9 For into this [situation] Christ not only died away, but also now lives, to the end that He would (or: should) be Lord (Owner; Master; Possessor) both of dead folks as well as of living people.
