The Faroes are still regarded as the minnows of Group C but took a point off Worthington's side in Toftir earlier in the campaign before pulling off a surprise 2-0 victory over Estonia.
They remain bottom of the standings, though, and a poor record away from home means Northern Ireland will be firm favourites to take three points at Windsor Park.
Worthington knows how important victory could be - it would leave his side two points behind second-placed Slovenia with a game in hand - but does not predict they will be allowed to run rampant.
"We need to win and to keep on the heels of the opposition. We still have a game in hand, that's what we are looking at and that will come through in the team," he said.
"But the Faroes will be well organised and behind the ball. It won't be easy.
"Patience, discipline and shape are important. You've got 90, 95 minutes to win the game but it has to be a controlled, disciplined performance. I think the term 'whipping boys' is disrespectful.
"Until the final whistle goes and you have the win in the bag then nothing is guaranteed.
"Our qualifier results have been very good and make no mistake it won't be easy but we will go and give a good account of ourselves."
Worthington admitted a sense of frustration lingers due to the draw earlier in the competition - a match that saw his side go behind before Kyle Lafferty equalised to avert a disastrous defeat.
"There was a lot of disappointment which came from losing two points to the Faroes because we created a lot of chances and didn't take them," he said.
"I know that because we got a point with an okay performance there will be disappointments but it's the same again this time. We had a fair amount of possession then, it's what we do with it that counts."
Worthington's preparations for the match have not been helped by a spate of absences and withdrawals in attack, with Chris Brunt suspended and
Lafferty (hernia), Josh McQuoid (hamstring) and Martin Paterson (thigh) all injured.
Warren Feeney is also unlikely to be fit for action, while James McClean became the latest player to reject a Northern Ireland call-up to pledge allegiance to the Republic of Ireland.
Worthington has refused to let those issues disrupt his planning and will rely on record-scorer David Healy, Celtic's Pat McCourt and uncapped Derby forward Jamie Ward to do the damage up front.
"Withdrawals are not an issue," he said.
"Kyle wasn't in the squad, Brunty as a forward-thinking player is a loss and about three of the five forwards in the squad have since withdrawn.
"But if they are not available through injury or whatever then that's the case, we have people in the right places to do the job."
