I heard some people (one pastor) say that it's impossible to go a day without sinning. Other people say that it is possible to go a week or even longer without sinning.

I personally think that it is longer to live through a day without sinning because of Matthew 5:48

"Be ye therefore perfect, even as your Father which is in heaven is perfect."

I think that this verse implies that it is possible to be as perfect as God. If it would not be possible to be perfect, then Jesus would say verse 48.

What do you all think about this topic?
