Actually, there is but one Gospel; (Good News) in four accounts from different perspectives telling the same accounts of Jesus' time on this earth.
The message is the same; salvation in Jesus Christ based upon grace from GOD for his children, that none should perish in their sins, but all can be brought back into fellowship with GOD through the perfect sacrificial blood of the only perfect man to ever walk the earth. It is a free gift, given in perfect love, for all who will accept it, and avoid perfect punishment for wanting to live a selfish, sinful life instead.
Be blessed,
