The Warriors booked their place in the Grand Final for the first time by downing Munster at Scotstoun on Friday night in front of capacity crowd of 10,000.
Now the Warriors travel to Dublin to face defending champions Leinster at the RDS, having lost there at the semi-final stage in 2012 and 2013, by four and two points respectively.
Scotland have endured a tough time of things of late on the international stage but Kellock believes victory for his side would breathe new life into the sport.
"This is important, of course it is. The fact we have brought 10,000 fans to Scotstoun is huge because we all want to see Scottish rugby growing and growing," he said.
"I have loved being part of it over the last 12 years but we are too hard on ourselves as a nation sometimes.
"We should really celebrate when things go well, so I think the supporters should enjoy this feat while we concentrate on winning this final and giving them something to really cheer about."
