There is only one God. The Bible is the infallible Word of God. The Bible states to be saved, which is to be born again, you must repent and be baptized in the name of Jesus Christ. When you are born again, you will receive the Holy Ghost, which is the Spirit of the Holy God inside of you, as evidenced by speaking in other tongues. The Holy Ghost inside of you will result in a lifestyle of holiness without which no one will enter Heaven.
