Why the release of this Book? There are many warnings in the New Testament to believers to beware of being led astray by false prophets and false christs. But ther are no direct warning of false church(es). Is this therefore the main reason why no one dares to question the indiscriminate use of the word(s) church and churches everywhere in the world? Actually the teachings and warnings of the Lord Jesus Christ in Matthew 13(see book no. 10) and Revelation chapters 2 & 3(see book no. 11) clearly revealed the rise of false churches and the progressive contamination of the true churches till all become false. In fact the Lord Jesus Christ called the false church - a synagogue of Satan. The prophecies of the Lord Jesus Christ concerning the rise of false believers and hence false churches and the progressive contamination of the true gospel till it becomes totally leavened, means a time will come when the true gospel becomes a hidden treasure. Once this stage is reached, it also automatically means that in most of the so-called churches there is no more true gospel being preached and taught. And since the church of the God is a pillar and support of the truth, without knowledge of the true gospel, how can true churches exist in public, if the true gospel becomes a hidden treasure? The reason for the release of this book is to reveal the true meaning of what is a church and what are the churches of the God. Only knowing the truth will true believers not be led astray in these the last days. This book reveals the truth concerning church and churches of the God by examining every scripture containing the translated word(s) "church" and "churches" and all other related words which also mean church or churches. Professing believers who read this book will then be able to test every so-called church or church organization to reveal if they are true church or churches of the God before they decide to fellowship in any of the churches existing in their locality or city. This book also reveal the danger of any true believer who continues to fellowship in a false church, because he will eventually be leavened with false teachings and will be led astray from the truth. In addition it has been shown that anyone who joins or fellowships with false leaders and false believers is considered to have left the first and foremost love, meaning has fallen away from the Lord Jesus Christ. Everyone who reads this book is urged to test its content against the unadulterated word of the God, in particular the original text of the New Testaqment in order to prove and/or to disprove its veracity.
