What about the caste system? Am I free from it after receiving the Lord Jesus Christ?

Our Indian/Asian culture can be very complicated. We who have been set free by the Lord Jesus can sometimes be led into errors by our culture. Our faith should always supersede our cultural views. We were all created equal by our Creator.
