Bible Believers And The Dispensation of Grace

A 2017 Gallup poll shows that only 24% of Americans believe that the Bible is the word of God. While this is not only detrimental to the country but also to each and every christian who claims to be one, this is caused by christians themselves. Many christians do not actually believe the Bible. They believe in a set of teachings or belong to schools of thoughts whether they be denominational or just what they got used to hearing while growing up. Then when challenged with what the Bible actually says, they think that the Bible is weird. Because of this attitude, it is easy for anyone who watches from the outside to come to the conclusion that the goalposts are indeed movable. If to the christian the Bible may be challenged and changed then what's to stop the unbeliever from not submitting to it either?
