The promises and blessings to Abraham are appropriated and fulfilled in Jesus. If we are born again by our faith in the finished work of Jesus, then we have those promises and blessings appropriated to us without being circumcised. Please read Romans 4. The whole chapter clearly refutes the argument you just made about the necessity of circumcision to appropriate the blessings and promises given to Abraham. After reading that whole chapter, please come back and explain to me what God was teaching us through His prophet and Apostle Paul.
