My family one my dad's side is hindu but my mom,dad,sister, and i are christian.HELP!

One piece of advice that I've seen recur over and over again in the writings of great Christians is: let nothing disturb. All you need to do is remain faithful. Also (1 Pt 4:14) "If you are insulted for the name of Christ, blessed are you, for the Spirit of glory and of God rests upon you." Don't think that something is going wrong. Your faith is being tested so respond to your family with kindness and a calm faith.
