The Midlanders face Norwich City and Chelsea in their next two games, and Lambert is hoping to have sealed his side's future in the Premier League before their final-day meeting with Wigan Athletic.
"That's the objective," Lambert told Sky Sports News. "I wouldn't like to go into the last game to try and stay up.
"We've put a lot of teams in the mix and pulled away from Wigan.
"We've played really well and that's all you can ask for at this stage of the season. I hope we can keep doing that."
Villa travel to Norwich City in their next match on Sunday.
