“And he received circumcision as a sign, a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but have not been circumcised, in order that righteousness might be credited to them.”
Romans 4:11 NIV
Today is Romans 4.

My husband and I started dating in the Spring of 92. We married after a whirlwind romance that occurred in what we fondly call our “Summer of Love.” (We married after 8 months, in January) I was 21 and he was 19.
It was during this time that Rich decided he wanted to seal the deal on our relationship and display that we were “a thing.” So as we were driving across an overpass not far from the campus house I lived in, he flipped his High School Senior ring up on the dashboard of the car and said, “Here you go! Put this on. It should keep the other boys from flirting with you.” Being 21 and having been in college for three years. I thought it was a little to “High Schoolish” for me, but I didn’t want to scare him off. (He was soooo cute!). So I put it on!
My heart was already his! We had a relationship. That ring was a sign and a seal!
For the Jewish people, Circumcision was meant to be just that! God wanted a nation that was His. This nation was to display Him, His glory, to the world around it. Circumcision was meant to be a sign and seal that the Jewish people were in a committed relationship with God. It wasn’t what made them righteous, or in right standing with Him. Righteousness only comes through faith! Not our deeds.
I could have wore that ring around back in 92 with my heart far from loving Rich. I could have hung out with him out of obligation or to get a free meal. Wearing it would have been hollow.
The circumcision that the Jewish people thought made them something special was only a hollow act if their hearts were not God’s.
They had the law. They followed the rules. But they weren’t obeying out of a heart that was connected to God through faith. They didn’t have the relationship!
