The Gospel and the Bible.
Without the Gospel there would be no Bible...BUT....Without the Bible there still would be the Gospel...THEREFORE...That which makes the Bible the written word of God is its witness to Christ and His Gospel because if there was no Gospel there would be no Bible!
If the Bible is abused and misused to prop up “another gospel” which according to Paul is not the Gospel at all, it fails in being a witness to Christ therefore, we have wrenched it from being the written word of God by misinterpreting it, and rendered it to a mere written word of man.
If we are Spirit lead in our reaction to the truth in the Bible, we without a doubt be drawn to Christ and our image of God will be as He presents Him for He is God as a man expressing Himself to man.
We need to be led and taught by His Spirit, who lives in the gospel, and then judge all things by His Spirit...even the letter of Scripture.
If we do not allow the Bible...the written word of God...to point us to...Christ the Living Word of God ( the Gospel Giver) the Bible is not used in the service of the gospel nor the service of Christ and the people misusing it will either find people mad (in their opinion) or make them mad in order for them to accept that the Gospel is presented.
Jesus and Paul both declared that apart from the Spirit it is impossible to understand truth (John 16:13; I Cor. 2:14). This means that unless we are Spirit led and Spirit fed we open ourselves up to “another gospel” and we cannot understand or use the Bible correctly. Apart from the Gospel the Bible is just written letters(gramma), not Spirit (pneuma). "The letter kills, but the Spirit gives life. Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom" (II Cor. 3:6,17).
