There are many reasons why numerous scholars have determined that the Gospels are both highly reliable and early-dated. On my “Christian Resources” page, under “T” for Textual Criticism and the Reliability of the Bible” you can find a wide assortment of informative links on this particular subject.
In this particular post I will highlight just two of these available links, both originating from reasonsforjesus.com. These two links provide an excellent overview on both the reliability of the Gospels and also their early dating.
As always, as believers who are always ready to give an answer to those who might ask, it is important to know why we believe, what we believe.
Worthy is the Lamb! Blessings!
