Tochacha and Love

Talmud Shabbat 89b Rava states that which it says in the pasuk in Yeshaya "Go  and Admonish says God" in future times God will tell Israel to go to their forefathers so that they can be reprimanded. Israel will say to God Who shall we go to? To Avraham to whom you said Yadoah Teidah that your children will be foreigners in Egypt and he didn't ask for mercy? To Yitzchak? He blessed Eisav and didn't ask for mercy. Yaakov didn't either ask for mercy etc. To whom can we go? Only to God! At which point God responds that since Israel put their faith in him he will erase their sins like red wool turning to snow.
The interesting point is that God sent Israel to their forefathers specifically for admonishment because of their love for their children. Israel's response was that even our forefathers love is not strong enough for us to feel that their admonishment is truly coming from the right place. Israel states that they need a stronger bond of love from their reprimander to fully accept it, and that can only come from God. This show of love to God is what allowed them to have their sins forgiven.
Even when you know that the reprimand is correct it will only really be absorbed if there is a bond between the admonisher and admonished. The stronger the bond the better accepted it will be
