Thank you, Ken. I've already looked at the Greek.
This issue has completely derailing the thread, so I think it might as well be dealt with at this point.
It seems that a few people who've responded to this thread are not just literalists, but read the texts literalistically. Here's a link to a very brief explanation of the differences between the two:

What is overlooked or misunderstood by people who take a literalistic approach are such things as poetry, metaphor and hyperbole, which "pray unceasingly" certain is an example of.
Rather than accept the idea that this is hyperbolic language, and in order to try to "make" it fit, they have had to change the very definition of the word prayer. (See some examples in previous posts).
Hyperbole was just as common back then as it is now. Jesus used this tool of communication often. Here are a couple of examples of Jesus using hyperbole.
"If your right eye causes you to sin, gouge it out and throw it away…"
The severity of sin is made very clear by Christ's use of hyperbole here. It's a sobering verse, but if we think it was intended to be taken literally then we should expect every single Christian to be eyeless, for what person can say that there eyes do not cause them to sin?
"You blind guides, straining out a gnat and swallowing a camel!"
We all know that a man can not swallow a camel. Jesus uses this to shock us - to wake us up. He's trying to make a point, and we do the same thing, e.g.,
"He's as skinny as a toothpick."
Here is one more:
"So the Pharisees said to one another, “See, this is getting us nowhere. Look how the whole world has gone after him!”
We know that the "whole world" did not go after Jesus, right?
In order to understand the message of the Bible we need to be good students of it. A student is careful to treat poetry differently than historical narrative, and didactic instruction different than metaphor. Is Jesus literally a door? Are we literally sheep?
This isn't difficult, but I think people can be so committed to treating God's seriously (which is a very good thing) that they have overstepped at times. In reacting to liberal theology, which began in the 19th century, and which takes very little of God's word literally, some well-meaning people have pushed back too hard in the opposite direction, and what was good-intentioned has become an equally, but opposite, error. Both the liberal theologian and the literalist leave us with a distorted view of the biblical texts. Neither helps us to properly understand the most important texts in a Christian's life.
