My definition is the same as Jesus'
Well im not trying to be too technical with you, but the verse there is really loaded
first of all the word sinner isnt used
second workers of iniquity is not the same as sinners
And the purpose was dual in what He was saying:
These people who didnt know Jesus were showboats
not just drunks or what have you, but actually
making a show to have great spirituals gifts
power. Wow what great work of iniquity
that is, yet its all around
