As per Gita 10.10 does Krishna help only those who serve him constantly and with love or does he help all his devotees?

From Achinta

I always have this doubt about Gita 10.10. In this particular verse Krsna specifically uses words like “satata yuktanam”, “priti purvakam”. Constantly engaged in serving me with love. Such is generally for the pure devotees and not for practicing devotees. So I develop the doubt that does Krsna really help as he poibts out in this verse. Is it meant for all or just for the pure devotees? Please clarify prabhuji.
