Jesus has already stated that the purpose of his ministry was in no way to destroy the Law and the prophets (that is, the Old Testament) but to fulfill them.
In this passage he begins to flesh out what that means. He seeks to bring the Old Testament law and teaching into its fulfillment by expounding its inner intent and purpose for the people of his own day. In “fulfilling” the law, he fills it up with meaning, demonstrating how it reveals to us the will and purpose of God.
John Wesley saw the Methodist movement as a return to the original life & faith & experience of Christianity. He wanted to return to the faith of the apostles and the early church — to find that same dynamic quality of faith and life that the early Christians had. So, Scripture had a place of central importance in Wesley’s teaching and preaching.
In Wesley’s view, devotion to the teachings of the Scripture is absolutely essential for the task of keeping and renewing the Christian faith.
So, in light of this, I’ve gathered together on this page everything substantive that John Wesley said about the Bible. I have not attempted to “tone down” or alter any of his opinions — though I have updated the language in the first quote. My goal here has been completeness.
Yes, there is some room for argument about what he may have meant by some of these remarks — of course. And, I certainly wouldn’t say the man was in any way infallible. A very valuable line of inquiry would be: how did this actually work out in practice, as he commented on Scripture in his Explanatory Notes.
