Old Testament is, "What's the deal with circumcision? What does it mean?"
We see this in Genesis 17:9-14. Click here to read it, then come back. I'll wait.
(Thought you'd never get back. Not a speed reader? Me neither...)
Why did God require circumcision:
1. As a sign of obedience to Him in all matters.
2. As a sign of belonging to his covenant* people. (*God promised to be with the Jews--His chosen people.) Once circumcised, there was no turning back. A man would be identified as a Jew forever.
3. As a symbol of "cutting off" the old life of sin, purifying one's heart and dedicating oneself to God.

Now aren't we all relieved Jesus is the way of a new covenant? ;-)
