As we look into the NewTestament we understand the OldTestament.
The name that has been profaned is the name of Jesus whom the God of the OldTestament has chosen for Himself Mat 1:21.
We see this clearly as there is no other name under heaven given among men whereby we must be saved Act 4:12.
When we address the HolySpirit in us, Who is also TheMajesty on high, we refer to Him as Jesus Joh 16:23.
SecularHumanists have proclaimed this `the post-christian era`. In so doing they have fulfilled this prophecy. And in so doing they will be destroyed on the DayOfWrath.
But this verse says that we (believers) also have profaned the NameOfJesus. How so? By refusing to call Him MightyGod, EverlastingFather and the one and only Saviour of the world.
Our Lord is depending on us to sanctify Him before the heathen. We do this by proclaiming the Gospel of Jesus Christ to every creature Mar 16:15.
