If he is going to maintain this level then hell yeah he should be kept at the team!

31 goals in 33 games so far in the season. It is just spectacular performance at the age of 36 you know.
Hansi Flick has made a huge impact on him I believe. He was away from this effort last season. I was also questioning whether he should stay anymore. But there is no question mark left at all now.
Even though he is older, he does not want to lose to other young players and his contribution is still quite good as an old player. There is no other reason for Barcelona to keep Lewandowski before they can get a player who has the same skills as the player. On the one hand, Hansi Flick does not want to take a big risk to change the line-up by replacing Lewandowski with a new player. While this season the player can still be relied on. So now Barcelona still has confidence and in the coming season may have to immediately divorce a replacement. Because the older he is, of course his performance will not last long.
