Abraham's token of justification by faith was CIRCUMCISION. God instituted Circumcision with Abraham as a token of His covenant with him and his descendants (c.f. Genesis 17: 10-14, Romans 4:11). For the Israelites the act of circumcision was a religious rite and serves to mark the beginning of covenant solidarity for the descendants of Abraham. Circumcision is symbolizes a consecration to the Lord and to the high moral standards of the covenant.
