You mean the one that you will not define? What about Mark 1:1? Why do you ignore this verse?
There are MANY gospels in the Bible and you do NOT understand what they are or how they relate to one another.
Stop falsely accusing and DISCUSS THE SCRIPTURE.
There is only one Gospel that justifies the ungodly Romans 4:5 and reconciles them (us) and the world unto God, 2 Corinthians 5:18, 19.
If you don't know or understand what this Gospel is, it may be that this Gospel is hid from you, 2 Corinthians 4:3, 4.
