If you knowingly, habitually commit sin...you have no business calling yourself a Christian.
She needs to read 1 John.
She could still be a Christian, but could have backslidden. I think that it takes more to be a Christian than just saying you grew up in Church and you pray every night and read the Bible. You have to live a different life. A life that will have a positive impact on people. Not a life that will cause them to sin also (the porn industry). It shouldn't be as popular as it is in mainstream America.
But to defend her profession and that it is not harmful to others, demonstrates to me that she has never met Jesus.
A 'backsliding' (hate that term Christiana would recognize what they do as sin.. This woman may some day be sieved but she is not generate.. She called evil good..
There is no place in the Bible that says the proof of your salvation is the past. The Bible says those that KEEP his commandments not those who kept his commandments...it says those who BELIEVE not those who believed. Read first 1 John again.
