there is no distinction [difference] between Jew and Greek [Gentile],
Jesus is Lord to both Jew and Gentile. God will save both the same way—by grace through faith. When it comes to salvation, there is no distinction about the availability of salvation. All men are alike in God’s sight when it comes to redemption.
Ro 3: 22 even the righteousness of God, through faith in Jesus Christ, to all and on all who believe. For there is no difference; 23 for all have sinned and fall short of the glory of God,

Christ has exalted universal Lordship over all. Both Jew and Greek must have the same way of salvation, because there is one LORD who saves and He never changes.
Ga 3: 28 There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus. 29 And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise.

Eph 2: 4 But God, who is rich in mercy, because of His great love with which He loved us,
Everyone who receives salvation receives the deluxe model.
There is no penal judgment for the Christian. Those who believe in Christ are declared to be as right as He is right. Because of this, no Christian will undergo condemnation from God (Ro 8:1). God gives salvation out of His unadulterated grace. He is no miser when it comes to declaring us as righteous as He is righteous.
