There is a famous video from a talk show in Tamil in which a woman shows up and claims she was born an Iyengar only due to great punya or some such thing. Is there scriptural support for the notion that God loves Vaishnavites more than others? And what do Southern Vaishnavites mean by "sarvebhyo vaishnavebyo namah" ("salutations to all vaishnavas") which they recite on religious occasions?
Don't get me wrong, but a lot of studying is required first. It is a bit odd when one asks 'does god love'. God is not a separate entity who loves and hates anyone. A person has to do good karmas to improve position in maya and thereafter, move on to higher realms of maya and maybe finally moksha or final exit from maya. Being Vaishnava is a state of mind that anyone can achieve. It cannot rightly be called a sect or group simply by being born in it as many mistakenly believe. As the famous bhaja 'vaishnava jana to tene', which was favourite of Gandhi Bapu, says, some of the characteristics of a vaishnava are that he/she will have sympathy/empathy for others, and help them without desire for rewards or developing any ego. (in short).
