Definitions
I have often seen (and taken part in) debates, where people basically agreed, but were arguing because they defined their terms differently, either using the same term to mean different things or different terms to mean the same thing. The words we use are often more of a reason for debate than our actual opinions. I think, therefrore, that it would be useful to define our terms to make sure we're all talking about the same thing. Even though it may seem obvious to us what these terms mean, it may be that others define them differently.
The first thing we need to define is what it means to "cease from sin". The way I see it, there are at least three possible definitions:
1. Ceasing from sin permanently. Using this definition would mean that a person who had ceased from sin would have reached a level of sanctification where he could say with certainty: "I will never again sin in all my life".
2. Ceasing from sin for a period of time. This definition means that we cannot know the future and therefore cannot say with certainty that we won't sin again, but each time we're tempted to sin we have a choice, either to give in and sin or to obey God and resist the temptation. If a person consistantly chooses to obey God, he could reach a point where he could say: "I have not sinned for the last <insert time period in weeks/months/years here>".
3. Ceasing from particular sins. Many people struggle in one particular area which they find very hard to control. It may be an addiction such as alcoholism or smoking or an attitude problem or any of a number of other things that they believe are sinful and which they can't seem to control. They might ask themselves: "Will I ever be able to stop committing this sin?" or "Will I ever be able to bring this area of my life under control?" Ceasing from sinning in this sense means that a person can reach the point where he can say "I had a serious problem with a particular sin in my life, but it is no longer a problem. I don't sin in that way any more."
Another term that needs to be difined is "sin". What people define as sin varies greatly and is affected by culture, denominations, experiences and other things. Some people limit their definition of sin to only actions while others include certain attitudes, thoughts, desires and emotions in their definition of sin. In addition to individual sins, the Bible speaks of sin as a force or power that influences individuals and the world as a whole.
What definitions we use will determine to a large extent whether we believe that we can cease from sinning. One person might say "We can cease from sin" and mean "We can stop committing sinful actions for a time, but can't be sure of the future", while another person might say "We can never stop sinning" and mean "We can never be sure that we'll never have sinful feelings again".
Even though we may disagree personally, I suggest that we agree to use one definition of "sin" and one definition of the phrase "cease from sin" for the purpose of this thread. And to make sure that we're actually answering the original poster's question, I would like to ask Pard to provide us with those definitions.
