1 Corinthians 8:4-6 "Therefore concerning the eating of things sacrificed to idols, we know that there is no such thing as an idol in the world, and that there is no God but one. 5 For even if there are so-called gods whether in heaven or on earth, as indeed there are many gods and many lords, 6 yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him."
To the Hindu, the whole point of their religion is to escape the endless cycle of Sanasara (some spell it "samsara") or Karma. In Hinduism, people are endlessly born, dying and being reborn as different life forms. Depending upon how morally one lives in this life and how much ritual one participates in will, in the Hindu mind, determine whether one has "good Karma" or "bad Karma". Karma is a Hindu word referring to "works or deeds" and is essentially a debt-based system of works salvation. Sansara is likened to a wheel of sorts, wherein a person keeps literally going around in circles. "Sansara" and its related concept "karma" portray a person trying to live good enough in this life to have a better spot in the next. The ultimate goal of Hinduism is to escape "Sansara" (which my friend readily affirmed in our conversation) and to achieve "Moksha" or union with the Universal Soul.
All who believe on Jesus do so because of grace, calling them and keeping them until they are in Heaven with Him. All who persist in unbelief and die and go to hell do so because of their own doing.
