According to the Holy Bible, there is one belief or faith: "One Lord, one faith, one baptism . . . " (Ephesians 4:5 KJV) They why do we have many beliefs among 2.2 billion Christians worldwide? Is it because the whole world has been deceived? What is the TRUTH? "And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him." (Revelation 12:9 KJV) "But if our gospel be hid, it is hid to them that are lost: In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them." (2 Corinthians 4:3 KJV) "And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in my name, saying, I am Christ; and shall deceive many" (Matthew 24:4-5 KJV). "For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him." (2 Corinthians 11:4 KJV) "Woe to the rebellious children, saith the LORD, that take counsel, but not of me; and that cover with a covering, but not of my spirit, that they may add sin to sin." (Isaiah 30:1 KJV) "And he will destroy in this mountain the face of the covering cast over all people, and the vail that is spread over all nations. He will swallow up death in victory; and the Lord GOD will wipe away tears from off all faces; and the rebuke of his people shall he take away from off all the earth: for the LORD hath spoken it." (Isaiah 25:7-8 KJV)
