Paul commands us to not conform to the pattern of this world but be transformed by the renewing of our mind. Because then we will be able to discern God's good pleasing and perfect will. And I do not believe it is possible to resist conforming or to be transformed or have our mind renewed or discern God's will unless we are regularly and consistently interacting with the Bible in ways that shape our inner core in the way of New Creation. If we are not consistently engaging with scripture and being shaped by it then inner transformation is a pipe dream and the renewal of our mind just ain't going to happen.
