Sometimes number 2 is the Christian thing to do.
That depends on what Rahab is being commended for. Is she being commended for lying, or for her faith in the God of Israel as demonstrated by her willingness to a) take the spies into her home and b) send them out a different way, believing their words that she would be saved if she followed their instructions?
One point that those who hold to an absolutist position make with regards to this proposed dilemma is that God is perfectly capable of protecting the innocent party if He chooses to do so. The classic example that is usually used, a variation on Minnesota's example, is lying to protect the Jews during WW2.
So, you're hiding a Jewish family in your home when Nazi officers knock on the door and ask if there are any Jews in the house. Do you a) lie to protect the family or b) tell the truth with the virtual certainty that they'll be rounded up and killed?
The absolutists would argue that you mustn't sin, so you mustn't lie. In response to the argument that you'd then be condemning the Jewish family to death, they'd respond that God is capable of protecting them - e.g. by blinding the Nazi's eyes to their presence. In other words, a graded position doesn't trust God enough. The question the absolutist would ask is this: Does God ever
require us to sin?
