³ Thou shalt have no other gods before me. (KJV)

In Exodus 20:3, God is giving his full permission for others to explore religion and find what works for them, or find what they truly believe in. This, however, is of course with a condition: you must be born a Christian, and then are able to freely explore and learn of other religions (or be an atheist before becoming Christian). As long as you find a god AFTER the Bible’s God, it is not a sin. The Word of the Lord. From the Big Man himself. (BBI)
