Those who are true believers in God's one and only Gospel are often confronted with the argument, 'Its just a doctrinal thing', when upholding the biblical standard that no one is saved who does not hold to the doctrine of Christ, which is His glorious Gospel. When it comes to the matter of Christ Jesus the Lord-Who He is and what He has done-doctrine is of immeasurable importance. It is a life and death issue that a person believes what GOD has testified of His Son, and not some man-made tradition, an imagination of man's mind concerning the Person and Work of Christ. This book will examine the statement, 'Its just a doctrinal thing' and explain why it is an assertion which is made in utter ignorance of the fact that when it comes to Who God is and which God/god one is believing and trusting in, doctrine can never be just a matter of opinion among equally saved people, or some irrelevant and inconsequential 'thing'.
