Jesus Christ prophesied that there would be great religious diversity in those who claim to be Christian and represent Him. Matthew 24:4-5 Matthew 24:4-5  And Jesus answered and said to them, Take heed that no man deceive you.
 For many shall come in my name, saying, I am Christ; and shall deceive many.
American King James Version×says, "And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in my name, saying [that] I am the Christ; and shall deceive many" (KJV).
As for the existence of the Church that Jesus founded in A.D. 31 on the Day of Pentecost, Jesus Himself promised that this church would always exist. Specifically, He said, "I will build My church, and the gates of Hades shall not prevail against it" (Matthew 16:18 Matthew 16:18And I say also to you, That you are Peter, and on this rock I will build my church; and the gates of hell shall not prevail against it.
American King James Version×). Therefore, God's Church does exist somewhere.
The Bible explains that this church will accurately reflect the teachings and message of Jesus Christ. It will be preaching His true gospel in the world (Matthew 28:19 Matthew 28:19Go you therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
American King James Version×; 24:14). By comparing what the Bible says God's Church will be like with the churches we see around us, we can discover where God's Church is today. Because this is a foundational subject that deserves much time and attention, we suggest that you write for our free booklet, The Church Jesus Built, or read it online . This booklet addresses these important questions in much greater detail.
