Matthew 5:17-18 17 "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished.
God's word written included IS truth. It was inspired by the Holy Spirit and being God He cannot lie.
Scripture does not just contain truth, it IS truth.
The written word is the special revelation to us by which we can come to Jesus and come to know Him.
***came to fulfill the written word***
And here I thought the written word prophesied the Word.
