This Book No. 23 is part of a series of separately titled books concerning the gospel of salvation on the CORNERSTONE teachings of Jesus Christ and the FOUNDATION teachings of the apostles/prophets. In particular this Book reveals the teachings of the Lord Jesus Christ and His apostles/prophets concerning the Greek word "krino" translated as "judge(d)." There is a popular teaching and widespread belief that true believers are not allowed to judge ("krino") other believers and they are especially not allowed to judge leaders of so-called churches in whatever they do and/or teach/preach. Some so-called church leaders even dare to preach that believers must not "touch the anointed of the Lord" thereby implying that they are the anointed of the Lord Jesus Christ. To support their teaching they often quote scriptures without understanding the true meaning of the Greek word "krino" and the application in its proper contexts. Such teachings contribute to the rise of lawlessness among so-called believers and so-called leaders of so-called churches. And such teachings certainly reflect that these so-called teachers and leaders of so-called churches that they established are not the churches of the God as defined according to the New Testament Scriptures. In Hosea 4:6 the God warned that His people perished for lack of knowledge and the reason was because the people had forgotten the law of the God. Because of this the God would also reject them and would also forget their children. There are many warnings given by the Lord Jesus Christ concerning the rise of many false prophets and false christs in the last days in Matthew chapter 24, Mark chapter 13 and Luke chapter 21. The Greek word "krino" translated as "judge(d)" in most English bibles has been used in three ways in the New Testament scriptures, namely: a) "krino" to mean "to discern/test/decide," b) "krino" to mean "to try as a judge," c) "krino" to mean "to condemn and/or to punish." This book contains the study of every scripture in the Greek Received Texts that carries the word "krino" and reveals its true meaning according to one of the above three meanings, interpreting the context of the meaning of "krino" and in particular its relevance to the gospel of salvation. The teachings of Jesus, Peter, Paul, James, John and in the Book of Hebrews concerning "krino" reveal what, when and how each believer should and/or should not "krino" concerning various situations and conditions each believer faces, giving the biblical basis for the believer to "krino." In particular the teachings reveal the importance for every believer to discern/distinguish/test/decide and/or to try as a juge and/or to condemn where and when it is necessary to do so. Failure to "krino" in circumstances can have fatal consequences on the everlasting destiny of the believer who faces such situations. However, true believers must be led by the Holy Spirit to "krino" accordingly. For example when the Jews failed to "krino" who Jesus Christ was/is, they had missed the opportunity to enter into everlasting life and the end result everlasting death and for the Jewish leaders the same condemnation was also upon their children. In the present time if true believers fail to "krino" the many false prophets and false christs and false believers and false churches existing in their midst and act according to the teaching of the Lord Jesus Christ and His apostles/prophets the true believers will be led astray into everlasting condemnation. This book reveals the many biblical examples and reasons why all true believers must fully understand the meaning of "krino" and they must not fail to "krino" whenever the situation(s) require(s) of them, in order that they not be led astray to everlasting death which are of particular relevance in this, the last days of increasing sins and increasing deceptions because of abundance of false prophets, false believers and false churches.
