How many covenants has God established with humanity and are any of them everlasting? I found this interesting partial quote from today’s Morning &amp; Evening devotional by Charles Spurgeon.  It’s about the “Covenant of Grace”:


  Jesus is the representative head of His people. In Adam every heir of flesh and blood has a personal interest, because he is the covenant head and representative of the race when considered under the law of works; so under the law of grace, every redeemed soul is one with the Lord from heaven, since He is the Second Adam, the Sponsor and Substitute of the elect in the new covenant of love.


Then I found this interesting snippet which, speaking of the pre-incarnate Jesus Christ, the Mediator, suggests that from eternity the covenant settlements of grace were decreed, ratified, and made sure forever.

My curiosity has been piqued.  Is the expression “covenant of grace” about the Abrahamic covenant established by God?  Or is it about the “New Covenant” introduced by Jesus?   Is this “an everlasting covenant”?  

I invite answers from Protestants on this topic, mainly because Spurgeon was a Baptist minister.  I would appreciate a short overview (links to articles would suffice) of all the covenants established by God and whether any of them are everlasting.

Edit: As suggested, this question is about Covenant Theology
Are any of them everlasting ?
There are thirteen references to the 'everlasting covenant' (KJV Old Testament) and one reference to 'the everlasting testament' (KJV New Testament) that I can find:
Either these are fourteen different covenants referring to a variety of everlasting matters ... or they are fourteen different aspects of the one New Testament, resulting in New Heavens and a New Earth and a New Inheritance in the World to Come ... a New Creation and the Resurrection from the Dead.
But none of these covenants (or, none of these aspects of the New Testament) is a matter of an agreement between God and the first humanity, that of Adam in the flesh.
The everlasting promises here made are established by Divine Promise without dependence on the response of humanity come out of Adam.

The above is extracted from previous work I wrote in 2012. A comment below from @curiousdanni enquires about the 'conclusions to be drawn' from the above. I cannot compress my previous work, so this is the link to the 100 or so pages titled 'The Everlasting Testament' (in PDF form).
