Comparison of Epistles and Gospels

Tonight, by the grace of the Lord, we want to see the relationship of the four Gospels, Matthew, Mark, Luke and John, to the Church Epistles. I believe that the greatest literary miracle of ages is the four, the presentation of the four Gospels. The thing that astounds me about the four Gospels is that they were written much later than the death, the resurrection and the ascension of Christ; many years after Paul had already received the revelation as to what the church of the body really was.
