This is perhaps the first book detailing the teachings of the Lord Jesus Christ on many key aspects of the gospel of salvation and the kingdom of the God, which had/have been concealed and not revealed as CORNERSTONE teachings of the gospel of salvation. The greatest consequence of this is the total contamination of the gospel of salvation while the true gospel or treasure has been hidden for centuries. The author has been discipled and led to write this book in the face of the full contamination of the gospel of salvation and the kingdom of the God, in order that believers may be revealed the true treasure so that they are able to understand the true gospel as taught by the Lord Jesus Christ. the Saviour of the world, when He was on the earth the first time. Only when believers understand and obey the truth of the gospel will they be set free from slavery to the sin. And only when those believers who are set free from slavery to the sin can they become sons of the God. And only sons of the God can remain in the kingdom of the God forever, meaning only sons of the God can receive everlasting life. The Lord Jesus Christ is the Road and the Truth and the Life. The Truth is the Word of the God. And in the New Testament days the main truth is the gospel of salvation. Therefore unless believers know(meaning understand) the truth concerning the gospel of salvation, how can they obey the truth of the gospel to receive everlasting life? And especially in the last days, unless believers know the truth of the gospel, how can they identify and reject false prophets, false teachers and false preachers who spread false gospel to lead them astray into everlasting fire? In view of the many different variations of translation and interpretation of the teachings of Paul, Peter, John and James regarding the gospel of salvation, it is imperative for believers to know and understand the CORNERSTONE teachings of the Lord Jesus Christ on the gospel of salvation and the kingdom of the God. There is a plethora of writings by "Christian authors and theologians and teachers" on the teachings of Paul on the gospel of salvation relating to the law and works and love and faith and obedience and perfection, etc. Many preachers and teachers of the Word of the God were/are confused themselves over such important issues. For believers to know the correct interpretation and translation of the teachings of the apostles and prophets on the gospel of salvation and the kingdom of the God, believers must know and understand the teachings of the Lord Jesus Christ on the gospel of salvation and the kingdom of the God. The main topics taught by the Lord Jesus Christ as revealed in this Book are: - a) Everlasting life, b) Righteous & Righteousness, c) Kingdom of the heaven and kingdom of the God, d) Save/Saved, e) Salvation, f) Resurrections, g) Live/lived, h) Die or perish forever, i) Soul - lose, gain or save, j) Judgement based on works, k) The gospel of salvation. Readers are urged to test the content in this Book against the Unadulterated Word of the God(the original texts of the Holy Bible) to prove and/or to disprove its veracity.
