This exerpt is taken from the July 15,2011 issue of the WT. Study article for Sept 19-25th.(BOLDING mines) This was under the subheading "When Someone We Love Leaves Jehovah"
16. Moses brother. Aaron, faced a difficult situation with regard to two of his sonds. Think of how he must have felt when his sons Nadab and Abihu offered illegitimate fire to Jehovah and He struck them dead. Of course, that ended any association those men could have had with their parents. But there is more. Jehovah instructed Aaron and his faithful sons: "Do not let your heads go ungroomed, and you must not tear your garments[in mourning], that you may not die and that [Jehovah] may not become indignant against all the assembly." (Lev. 10:1-6) The message is clear. Our love for Jehovah must be stronger than our love for unfaithful family members.
17. Today, Jehovah does not immediately execute those who violate his laws. He lovingly gives them the opportunity to repent from their unrighteous works. How would Jehovah feel, though, if the parents of an unrepentant wrongdoer kept putting Him to the test by having unnecessary association with their disfellowshipped son or daughter?
So looking at the bolded text, although they do not say bluntly say "Jehovah is being loving towards His people today unlike the UNloving way he dealt with people in the past...", is that not the implication of the way this text was worded? In effect, saying, "Nadub and Abihu were struck dead immediately for violating God's law. But today, rather than the harsh and unloving way He dealt with Nadub and Abihu, 'He lovingly gives them the opportunity to repent from their unrighteous work'". That would obviously be contrary to Deuteronomy 32:4, which says "The Rock, perfect is his activity, For all his ways are justice. A God of faithfulness, with whom there is no injustice; Righteous and upright is he.".
