Manager Allan Johnston was relieved that his team's stout second-half defensive performance earned Kilmarnock a Scottish Premiership point to end a run of five straight losses.
The Ayrshiremen had taken the lead when Tope Obadeyi poked home the rebound from Paul Gallacher's impressive save from a Lee Miller snap-shot.
However, the Jags captain Daniel Seaborne was afforded too much space in the Killie box, allowing him to head home an equaliser eight first-half minutes later.
"It was a big point for us," Johnston told BBC Radio Scotland.
"It gives the boys a bit of confidence and now they've got to build on that. We've got a home game next against St Johnstone and we're going into that full of confidence and wanting to win the game.
"You can see how much it meant to the players. They gave everything and you can't ask for any more.
"Every person worked their socks off. They give everything for the team, we defended really well, and we have to take that into the next game.
"I don't think both teams had a lot of clear-cut chances. In the second half we were under a lot of pressure but we defended really well. We know that we can improve."
For home boss Alan Archibald, there was the gnawing feeling of having missed out on two points more.
"I thought we were going to nick it at the end," he said.
"I thought James Craigen was going to score. On another day he could have.
"It's been a pleasing aspect that any time this season we've lost a goal we've got back into as quickly as we could.
"In the second half, I don't know if it was the conditions or two teams cancelling each other out, but I thought it was a poor spectacle."
Though the second 45 minutes was devoid of much craft, there was some good passing football in the first half, especially from Thistle.
"It's something we harp on about all the time," said Archibald of the passing. "But we also say to them there's got to be a final ball.
"We've got to have that killer instinct. We're urging them to shoot more and cross more. Sometimes it can be a bit pedestrian so we're trying to get them to speed up the play to hurt teams.
"The performances have been good. Over the last two months I think they've picked up, but it was a sore one because we were desperate to win this game and get closer to Kilmarnock and Dundee who are just above us."
