"We were not fathers also to convey the promise, as Abraham was; nor although the promise, as collectively taken, had belonged to us, as to Abraham it did"

This quote by Thomas Goodwin is referring to the pledge of salvation that was given to Abraham in the Bible. Goodwin is stating that although the guarantee of redemption was provided to Abraham, it does not necessarily indicate that it is given to us also. He is stating that we are not daddies in the very same method that Abraham was, and that even if the promise of salvation was given to us jointly, it would not be the same as it was for Abraham. Goodwin is stressing the importance of Abraham's role in the guarantee of salvation, and how it is not the same for us. He is also highlighting the fact that although we might have the same pledge of salvation, it is not the like it was for Abraham.
