Baptized Hindu

I was born a Hindu and after some painful moments in life, began reading the Bible and am now baptized. Since becoming Christian there is more peace and calm in me and I am also becoming more successful in my career. I feel like I have to somehow bring my parents, brothers, sisters, nephews and nieces to know Christ as well. With the exception of a sister, the rest are Hindus. Is this my responsibility? Is this what God would want me to do? I love being Christian and now I am beginning to see my siblings as belonging to the “other camp”.
