This law was "the partition" or "fence," which embodied the expression of the "enmity" (the "wrath" of God against our sin, and our enmity to Him, Eph 2:3) (Rom 4:15; Rom 5:20; Rom 7:10-11; Rom 8:7). Christ has in, or by, His crucified flesh, abolished it, so far as its condemning and enmity-creating power is concerned (Col 2:14), substituting for it the law of love, which is the everlasting spirit of the law, and which flows from the realization in the soul of His love in His death for us.
