We know, or hopefully should believe, that the scripture are the only infallible, sufficient rule of all saving knowledge, faith, and obedience, and should be looked toward and studied as it is so (II Tim 3:15-17). It sounds simple but to formally state it anyway, one should study His Word. Anything you hear or read from any other source should be suspect. I am not rejecting all references and other books written, for God has used many of them to illuminate His word more clearly. I myself would struggle without a good concordance and Vine’s Dictionary or even many of the other excellent commentaries and articles grounded in the doctrines of Grace. That said they are not replacements for His word and do only to focus us on His message. Always look back to the scriptures and be careful of rantings of men that do not support what they say in the Word of God. You should never believe based on what a man said but seek for yourself and believe because the Bible says (Isa 8:20). Take nothing on the faith of the flesh but continue to search the scriptures for yourself to see what the Spirit teaches (I Cor 2:12-13). For in them is all truth and wisdom and if it pleases God He shall open up our understanding so that His truths might be revealed (Luk 24:45).
