Many believers live by this motto. Often times saying well I am not a bible scholar or a theologian. Be that as it may I would advise you to follow the advice Paul gave to a young Timothy. I know that many would argue that this advice is found in a pastoral letter given by Paul to Timothy (A Minster of the Gospel). Be that as it may we all handle the Word of God in some capacity. Whether it is as a head of a Sunday School Class, bible study, or head of a household I would encourage you to follow the advice of the Apostle Paul. For there are many false teachers out there and not all of them have evil intentions. The Bible states that people perish because lack of knowledge. The Bible ultimately reveals the character of God, his will for his children, and instructions to survive. Understanding the truth of the Word of God is vital to your spiritual survival!! Therefore follow the advice of the Apostle Paul.
What is this advice you asked? Study to shew thyself approved unto God, a workman that needed not to be ashamed, rightly dividing the word of truth.
