Should Christians study the Gospels even though there is no Church doctrine in them?

Les explains that when Paul wrote his epistles, the Gospels likely had not yet been written or gathered as Scripture, so Paul’s references to “Scripture” or things “written aforetime” meant the Old Testament. Les clarifies that he never told anyone not to read the Old Testament or the Gospels; everything written before Paul wrote is for the believer’s learning, and he says the same about the Gospels. Although the Gospels do not contain Church doctrine, that does not mean we do not study them or make application. Les gives the primary application: when Jesus spoke to the twelve on the northern shores of Galilee, He used the illustration of a city on a hill and said they were the light of the world. Israel was promised to be the light of the world but rejected that opportunity. Now, by application, believers are the light of the world, so we can still make the same application.
