Apart from having the Holy Ghost who teaches us all things and like him we compare spiritual things with spiritual.
1Cor 2:13 Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
We also need our God given tool box, and in that tool box are the seven tools to study and rightly divide the word of Truth.
these tools are Who, What, When Where, Why, Which and How.
Are you studying the way God wants you to or are you just following what other men say?
Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. 2Ti 2:15
