Uh, no she can't. Who is the father of lies? (John 8:44). If a person lies like the father of lies, does that mean they are of God the Father or they are of the father of lies? Who is worthy of death in Romans 1? Those who are full of all unrighteousness... deceit. All liars will have their part in what place according to Revelation 21:8? The Lake of Fire.
For one, Rahab did not lie according to the 9th Commandment. The 9th Commandment considers a lie as done for self centered and or sinful reasons.
She obviously lied and was an example to us for the faith, face it.
It was not held against her, I dont even hold it against her, I would do the very same thing and be perfectly fine about doing it, she is my example in the faith.
I dont think even when Abraham was instructing Sarah to withhold the full truth it was held against him anymore then Isaac doing the same with his wife (who wasnt his sister). Theres other places where I dont see the same done in faith so much, like in King Zedekiah instructing Jeremiah what to say seemed okay there, but Davids lie to Ahimelech caused some problems, although that was not mentioned in 1 Kings 15:5
If you sought refuge with me and wanted me to hand you over to the one seeking to kill you (I would if you wanted me to) but naturally I would try to hide you and lie my tail off as to where you are.
I tell the truth ( I would lie)
Therefore am I a liar by telling the truth?
lol
