What is the 'grey area'? I think of the grey area as man calling sin good. However, God still sees sin as sin. There is no grey area with God.

Yesterday I heard on the radio about one man, who I will not name, being called a Christina but then saying Jesus would saction sin.

How can someone call themselves a Christina and then say sin is good?

To me this is not a sign of a Christina. Remember in the Bible: For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.  Revelation 22:18-19

If you claim to be a Christian, guard your minds from the evil of this world, and do not call sin good. We will all be judged.
