The Greek implies to compress forcibly the energies into one channel. Love is jealous of any rival object engrossing the soul (Co2 11:1-3). because we thus judge--literally, "(as) having judged thus"; implying a judgment formed at conversion, and ever since regarded as a settled truth. that if--that is, that since.

His dying is just the same as if they all died; and in their so dying, they died to sin and self, that they might live to God their Redeemer, whose henceforth they are (Rom 6:2-11; Gal 2:20; Col 3:3; Pe1 4:1-3).
