Does God have one right choice for me in each decision I make?
Many Christians who struggle with this question today are unaware that Christians of the past can help them from their own experience. Christian wisdom embodied in the lives and teachings of the saints tells us two things that are relevant to this question.
First, they tell us that God not only knows and loves us in general but that he cares about every detail of our lives, and we are to seek to walk in his will in all things, big and little. Second, they tell us that he has given us free will and reason because he wants us to use it to make decisions. This tradition is exemplified in Saint Augustine's famous motto "Love God and [then] do what you will." In other words, if you truly love God and his will, then doing what you will, will, in fact, be doing what God wills.
Do these two pieces of advice pull us in opposite directions, or do they only seem to? Since there is obviously a great truth embodied in both of them, which do we emphasize the most to resolve our question of whether God has one right way for us?
I think the first and most obvious answer to this question is that it depends on which people are asking it. We have a tendency to emphasize one half of the truth at the expense of the other half, and we can do that in either of the two ways. Every heresy in the history of theology fits this pattern: for instance, emphasizing Christ's divinity at the expense of his humanity or his humanity at the expense of his divinity; or emphasizing divine sovereignty at the expense of free will or free will at the expense of divine sovereignty.
Five general principles of discernment of God's will that apply to all questions about it, and therefore to our question too, are the following:
