A crossroad is reached, and a relationship changes. One way or the other. You wake up in a hospital with tubes and wires everywhere, and you are at a crossroad - there are choices to be made, not just about medical care but about to react to adversity, and whatever you choose will change you, one way or the other. Satan tested Jesus and through those tests or temptations, Jesus learned what it really means to be the Messiah. When God leads us to a crossroad of temptation, it is to teach us something.
Every temptation is an opportunity to grow spiritually.
The wife in our earlier drama is at a crossroad, and she faces an opportunity to grow. For many of us, perhaps for all of us there is a certain weakness in our characters which rises over and over again to tempt us. Like a rabid hound from hell, the same temptation comes back over and over again until we get it right, until we learn what we need to learn. Sexy women will keep batting their eyes at a lustful man until he learns to say no, until he take the road that leads to home and real intimacy with his wife. And it seems like everywhere an angry person turns people are trying to get on their last nerve.
