How Many Gospels?

How many Gospels? Just how many gospels are there that a person can believe, safely place their trust in, and rightly consider themselves saved of God? Five? Ten? Twenty? Or perhaps hundreds? Just how many gospels are there that God will lead a person to believe ie. grant the gift of faith to believe? How many gospels are there to which God signs His name and calls 'My power unto salvation'? These are questions that strike right at the heart of the whole issue of doctrine, of what the true Gospel is, and who it is that can rightly judge themselves saved. It is important to realise at the outset that what a person believes about Jesus provides an immediate indication of which jesus they believe in, and therefore which gospel they hold to.
