Jews-and-GentilesRom. 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
There are two groups of people in the Bible.  Contrary to traditional belief, the two groups are not saved people and unsaved people, neither are the two groups believers and unbelievers.  The two groups are Jews and Gentiles.  The Bible also refers to the groups as circumcised and uncircumcised, respectively.  Why is it important to understand the distinction?  Because it helps us understand the kingdom of God from God’s perspective.  We learned earlier that the commands and statutes were given to Israel and no other nation, a truth that Paul affirmed in his epistle to the Romans:
Rom. 3:1  Then what advantage has the Jew? Or what is the value of circumcision?Much in every way. To begin with, the Jews were entrusted with the oracles of God.
God declared only one nation of people on earth to be holy, and that was the Jews.  The promise of the kingdom was given and entrusted to the Jews.  The covenants were made with Jews.  Gentiles had no part of the promises, a truth that Paul affirms in his letter to the Ephesians:
Eph. 2:11 Therefore remember that at one time you Gentiles in the flesh, called “the uncircumcision” by what is called the circumcision, which is made in the flesh by hands— 12 remember that you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world.
Paul makes us face a hard truth – the Gentiles, or uncircumcised, were without hope and without God in the world.  We were born separated from God, no matter how we describe ourselves.  So what do atheists, people of other faiths, unbelievers and most Christians have in common?  All are uncircumcised.  When we are able to face this truth, we realize the extent of God’s mercy on the lives of all people.  This is why it is of extreme importance to share the kindness of God with others, for as we learned, it is his kindness that leads us to repentance.  As Gentile Christians, we should be the living definition of God’s mercy!  For if God extended to us mercy and compassion, how much more should that mercy and compassion be exhibited in our lives toward others?
