When initially training those who work with electricity or natural gas, very specific instructions must be learned and understood. Even a minor mistake can result in death or destruction. Multitudes of things can only be done one way.
Hence all good instructors understand the need for very general commands when the task is easy and simple. They reserve specific commands for complicated tasks requiring step-by-step guidance. It doesn’t matter what the occupation is - a student, mechanic, doctor, nurse, electrician, mechanic, manufacturer, or chemist all need such general and specific instructions.
Yet when Christians speak of general and specific authority/commands, as a means to understand Scripture, they are treated as though they have created something new and novel. Is it really novel to think that God would use the same principles to guide us to heaven? Scriptures contain the most important of all instructions! Eternal life or eternal condemnation will result from how well we follow them. Can anyone believe that our loving Creator, who wants “all to be saved and come to the knowledge of the truth”, would not word His commands and instructions so we can succeed? Is everyone so experienced that God doesn’t need to give step-by-step specific instructions to us? Are the things God has asked us to do so simple we only need general commands? Since God long ago revealed that it is “not in man to direct his own steps” and that “My thoughts are not your thoughts, Nor are your ways My ways,” that is clearly not the case (Jer. 10:23; Isa. 55:8).
