Actually, a will is a specialized form of promise, a recorded promise, if you will, where upon the occurance of an event, property will convey from one person to another. While the details for any given reference should not be ignored, making too sharp a distinction between covenant and testament will tend to obscure more than it illuminates.

No, because the Bible makes it very clear that a testament isn't into effect until there is a death of the testator.

That isn't the case for a Covenant.

Heb.8 is speaking to Israel (note the words Israel and Judah in Heb.8:8) and isn't referring to our present salvation.

What is 'old' and done away is the old Mosaic covenant.

The Bible is the Old and New Testament, not Old and New Covenant.

[PapaNew]

fortheDeclaration is trying to completely separate the new testament from the new covenant. I suppose you can say they are different because a testament is a will that contains promises and devises which are covenants. But the two go together and really are hard to separate conceptually as you say.

Separating the two is a novel concept to me and not according to the real world or scripture (Heb 7-10 among others) and leads to heresy which always happens when basic Biblical truths are denied.
