Our Sunday School group is studying the book of Romans. In searching for a deeper understanding of why God told Abraham to circumcise his household, I came across your article on circumcision.
I feel the article was very helpful to me to understand this sign of the covenant that God made with Abraham. And I thought it very informative on viewing baptism as a New Covenant form of circumcision as it is the sign of our covenant with Jesus Christ.
I'm always glad to hear that the answers have been useful to people.
