Justified Lies?

In order to evade pursuers and find lodging one time, Parley P. Pratt told some untruths. He justifies this with the following:

"I would here remark that some persons will perhaps be disposed to censure me for saying that which was not strictly true in all its points, in order to avoid discovery, and make good my escape. But I can say, from the bottom of my heart, that I feel perfectly justified in so doing, not only because it accomplished a good object, and seemed according to wisdom, but we have numerous instances in Scripture where God's prophets and people acted in a similar way for a similar end. For instance, the New Testament justifies Rahab, and even commends her, and includes her in the sum of the faithful, because she hid the spies under the flax and deceived their pursuers by stating that they had left the city and fled to the mountains; and thus she became an accomplice, or an aider and abettor of the people and purposes of God. David also, who was the Lord's anointed, and a man after his own heart, dissembled a number of times to save his life. At one time he deceived the national priest, and thus obtained both bread and armor, under pretense of being on the king's errand, while he was in fact an outlaw, then in the act of fleeing for his life from that same Saul. And Jesus himself mentions this to the Jews, and justifies it. At another time he feigned himself insane, by figuring on the wall and letting his spittle drizzle down on his beard, in order to escape the Philistine judges."

I really liked the phrase "an accomplice, or an aider and abettor of the people and purposes of God". Perhaps lying is justified, when it furthers the purposes of God? What think ye?
