Response A
Some argue that the covenant in Judaism is universal meaning that anyone can be part of it.
In Genesis God made a covenant between Adam and Eve when they were created but they did not do as they were told. Also Noah was saved with his family from the flood.
Others say that the covenant in Judaism is not universal. Abraham was called by God and God promised him many descendants. They were given the sign of circumcision as a symbol of this covenant agreement. Abraham also was so close to God that God asked him to make a sacrifice of his son.
In conclusion I think the covenant is just for Judaism as no-one else really practices the things associated with it today. It is also very religious and not relevant to those who are not religious.
