Everyone has turned away [from God]. All of them have become worthless. No one is [always] kind; no, not even one person."

So, look at God's kindness and severity. He was severe with those [Jews] who have fallen, but He is kind to you [Gentiles], if you continue to accept His kindness [i.e., by living for Him faithfully]. Otherwise, you too will be cut off [like the Jews were].

And I, myself, am convinced about you, my brothers, that you yourselves are full of goodness, and have been filled with all kinds of knowledge and are capable of counseling one another.
