The Reds have been plagued by inconsistency this season but back-to-back wins in the Premier League, against QPR and Sunderland, have boosted their confidence, and Brendan Rodgers' men are fully expected to come away with the victory against Mansfield.
However, despite the supposed gulf in quality between the two sides, Henderson has urged his team-mates not to underestimate the Stags and claimed the Conference side would push them all the way on Sunday.
"It'll be a tough game for us," Henderson was quoted as saying by the official Liverpool website.
"It won't be a pushover. We will have to go there with the right mentality and do a good job.
"It'll be different to what we're used to in the Premier League. But you always have different challenges in football.
"If we play like we are, then we can get a positive result."
With Liverpool set to play at Mansfield's home ground, the One Call Stadium, which has a maximum capacity of 7574, Henderson knows that his team-mates would have to get used to playing in front of a smaller crowd than what they were used to.
"We'll have to adapt to the situation," Henderson added.
"I'm sure all the players will have played at small stadiums like that before, and it'll be a good atmosphere.
"It'll be noisy. We have to make sure we are on it from the very start and try to keep the home fans quiet.
"It'll be the biggest game for many of those Mansfield players.
"They'll be really up for it. It'll be a cup final for them, so we have to treat it as a cup final for us and do the job properly."
Henderson, much derided by the media for his substandard performances when he first joined the club in 2010, was given a standing ovation by the Liverpool fans when he was substituted in his side's clash with Sunderland, and the 22-year-old hailed the unconditional support he had received from Liverpool fans over the past two years.
"It meant a lot to be given that ovation by the fans when I was substituted," Henderson proudly reflected.
"The fans have always been behind me since I came here. Things are going well for me at the moment."
Henderson has thus far made 50 appearances for the Reds in the Premier League and 5 appearances in the FA Cup, scoring two goals in the process.
