Why the need to release a book concerning the translated word "faith" when all professing believers will tell you that it is because they have FAITH that identifies them to be called Christians? But hardly any professing believers especially those who believe in a gospel that says they are "saved by grace alone and through faith alone and not by works" realise that they have a FAITH that CANNOT BE SHOWN TO BE GENUINE OR TRUE, nor can their FAITH be VERIFIED according to the unadulterated word of the God, the original Greek Received Texts. This means the majority of the so-called Christian sects which believe a gospel that salvation is by grace alone and through faith alone and not by works have a FAITH that is UNCLEAR and CONFUSED. That is why many preachers have led masses of listeners to utter the sinners' prayer such including Romans 10:9-10 and then declare those who make such confession to be Christians and therefore they are in the kingdom of the God How can anyone prove or confirm that the preaching of such so-called men of God who led masses of people to utter the sinners' prayer that the conversion of those masses to become Christians are genuine believers or genuine Christians? There had/has been so much confusion for so many centuries and more so today in the so-called Christianity concerning many issues such as 1] the many Christian sects and the different variations of the gospel being preached, which one of them is true or are they all false? 2] the many so-called Christian leaders today, which of them are true and which of them are false? 3] of the so many so-called churches today in the same city, which of them are true and which of them are false? 4] of the so many so-called professing believers or so-called Christians, which of them are true and which of them are false? The teachings of the Lord Jesus Christ in Matthew 7:13-20; Matthew chapters 13 and 24; Mark chapter 13; Luke chapter 21; Revelation chapters 2 & 3 and the warnings by the apostles, Paul, Peter, John and other writers in the New Testament concerning the rise of false prophets, false christs and false teachers in the last days deceiving many to damnation. All these teachings and warnings seem to be IGNORED and fallen on deaf ears. If you are a true believer into Christ are you able to identify the many false prophets and false christs, false churches and false believers today that are in your midst? Or are you yourself a false believer? The above are the reasons for the writing of this Book 29 concerning FAITH. Is it FAITH OF GOD or FAITH OF MANKIND that is required for anyone to become a true believer into Christ Jesus? Can mankind's own faith in the God lead mankind to salvation? What is faith of mankind and what is faith of God? Is faith in general related to works in general? Can believers have faith in God and yet show no works? What is genuine faith in God? Does a believer have to have a perfect faith to be saved? What is the difference between 'faith' and 'the faith' and their relation to the gospel of salvation? How can anyone have faith in Christ in order to become a true believer? If true believers do not have clarity in understanding faith of mankind and faith of God, the faith and their relationship to the gospel of salvation, how can anyone be confident that he is earnestly contending for the faith once delivered to the true believers in the days of the apostles of Jesus Christ? The above are the reasons for the writing of this Book which should enable true believers to have clarity to the understanding of 'faith of God', 'faith of mankind', 'the faith' and their relationship and importance to the gospel of salvation.
