I have learned so much about this from Carson, especially number 5:
Balance in Integrating Complementary Truths That Lie on the Edge of Great Mysteries, Not Least Complementary Truths about God
God is unfathomably loving, yet his wrath reflects his perfect justice. He is utterly sovereign, yet he personally interacts with other persons, not least the human beings he has made in his own image, such that he holds them accountable for what they say and do and feel and imagine; for sovereign though he is, he never treats them as insensate robots. God is one, yet he exists as three persons who interact with one another. Even to begin to make sense of these complementary truths, it is not long before one is wrestling with the relationships between time and eternity, with the nature of secondary causality, with the nature of the will and the nature of freedom, with the notions of person and substance. Part of the aim of biblical balance in these cases is to learn to state the complementary truths in such a way that one is not unwittingly undermining something else that Scripture says. One refuses to draw inferences from one facet of the truth that endangers some other facet of the truth. One learns to let each truth function in our lives and in our theology in the same ways they function in Scripture, and in no other ways.
