Gerrard will lead the Three Lions out at Wembley against both Montenegro on Friday night and Poland next Tuesday, with the aim of collecting six points to guarantee their qualification from Group H.
Unbeaten England lie top of the standings by just one point ahead of Ukraine and Montenegro but have had their credentials questioned after a couple of lacklustre performances in the group under manager Roy Hodgson.
Indeed, their only victories have come against minnows Moldova and San Marino, but Gerrard is well aware the players need to be at their best in the qualifying double header.
"They're up there with the most important games I've played for England in the 105 I've already played," he told a press conference.
"We're at a critical stage of the qualifying campaign now and it's up to myself and the players to deliver. They're very important games."
It promises to be a day to remember for Gerrard, who will move joint fourth - alongside Bobby Charlton - on England's most capped players with his 106th appearance against Montenegro.
"I'm very proud. He's one of the best players to have ever played for England so to equal his record is very flattering and I'm honoured," Gerrard added.
"Hopefully it'll be a good memory as well and we can get the win we need."
Four teams - England, Ukraine, Montenegro and Poland - still harbour realistic hopes of finishing top of the pile and book their spot at the World Cup come next Tuesday.
With England taking on Montenegro, the other group game is no less enticing as Poland look to avenge their only defeat of the campaign against neighbours Ukraine, who triumphed 3-1 when the sides last met in Warsaw.
Mykhaylo Fomenko took charge of Ukraine for the first time in that match and has coached them to an impressive four wins and a draw during his time in charge.
He acknowledges that Poland will be champing at the bit for revenge in Kharkiv.
"We know our opponents are very angry after that home defeat," Fomenko said on uefa.com. "Our lads know that, yet they need no extra motivation.
"It will be tough but so will the other fixture - England against Montenegro."
FIFA had initially ruled the match to be played behind closed doors following investigations into racist behaviour during a game against San Marino.
But the governing body last week granted suspensive effect as its appeals committee would not be able to reach a decision early enough.
Elsewhere in Group H, Moldova will host outsiders San Marino who have scored one and conceded 43 goals in eight matches so far.
Ion Caras' men won 2-0 their previous encounter with San Marino and have managed to frustrate Ukraine and Poland with draws at the Stadionul Zimbru in this qualification campaign.
