Billions believe in and practice a form of Christianity that may not be in accordance with the definitions in the Holy Bible. Jesus Christ often warned most emphatically that many would be deceived into embracing false forms of worship. "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". All 'religions' consist of human ideas about how to worship God. However no fervent, sincere Christian person thinks that they are deceived. Christ must have meant someone else! Frightening fact: Anyone, including those who attend Church, who is deceived, does not know they are deceived. A counterfeit is so like the real thing that it takes careful research to be able to tell the difference. If anybody is following a counterfeit gospel, it will not be easy for them to believe or accept that fact. There are thousands of denominations of Christianity, each preach their own conflicting set of doctrines and beliefs, they cannot all be right. What is the solution? Any person who would be a true Christian cannot rely on any human organisation with human teachers for their source of truth. There is only one standard that can be relied on, God's own Word to us. The Holy Bible is the only Book in the world in which God speaks to us in the first person. "Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me. Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:". 'Theology' is literally the study of God and true Christianity through His Word. Even there, a person has to be careful as all translations contain serious errors which can and do lead readers off the true path to Christianity. This book does not attempt to tell the reader what to think or believe, but will help the earnest person to find the truth for themselves.
