Basic Definitions of the Gospel

Here are some more basic definitions of the gospel that I have come across on the internet. What do you think of them? What would you add, subtract or change?

C. J. Mahaney
“The gospel is the good news of God’s saving activity in the person and work of Christ. This includes his incarnation in which he took to himself full (yet sinless) human nature; his sinless life which fulfilled the perfect law of God; his substitutionary death which paid the penalty for man’s sin and satisfied the righteous wrath of God; his resurrection demonstrating God’s satisfaction with his sacrifice; and his glorification and ascension to the right hand of the Father where he now reigns and intercedes for the church.

Mark Lauterbach
The Gospel is fundamentally a message that God has undertaken to accomplish by himself alone what the combined sweat and labor of the entire race of mankind has been unable to do -- to rescue us from the evil within us and its consequences.

Scott Mackay
The great news of the Bible, the gospel, is that God's dynamic rule has broken into history through the coming of King Jesus; the King who "died for our sins in accordance with the Scriptures, was buried, was raised on the third day in accordance with the Scriptures" and appeared to the apostles whom he chose to be reliable witnesses of these things.
