"... having forgiven us all our transgressions, 14 He ABOLISHED THE HANDWRITTEN LAW OF ORDINANCES consisting of decrees against us, which was hostile to us; He took it out of the way and nailed it to the cross disarming the rulers and authorities and publicly humiliating them, thus triumphing over them IN IT" --- "IN IT" : in ABOLISHING THE HANDWRITTEN LAW OF ORDINANCES consisting of decrees against us, in TAKING IT OUT OF THE WAY AND NAILING it to the cross, Christ "IN IT", disarmed the rulers and authorities and publicly humiliated them and "TRIUMPHED".
Yes, God >through Him< triumphed; but CHRIST through or in having done THESE THINGS with regard to the Law and WITH THE LAW, "IN IT, triumphed".
You said “through Him” so that it would appear Christ did not “triumph” in having ABOLISHED THE LAW. Well, that is corrupting the Scriptures which actually shows contempt for the Law instead of respect for the Law.
