“For what does the Scripture say? Abraham believed in (trusted in) God, and it was credited to his account as righteousness (right living and right standing with God).” Romans 4:3 IOW – The passage goes on to say that God credited this righteousness to Abraham before he was circumcised; that circumcision then became an outward symbol of Abraham’s belief in God and the credited righteousness he received. Whether you are circumcised or not (Jew or not) you also receive God’s righteousness credited to you through belief in His son and because of Jesus your sins will never be counted against you (Romans 4:7&8). Mind boggling.
