Truth for everyone is found in Romans 3.
There is no difference between Jew and Gentile, circumcised or uncircumcised because "all have sinned and fall short of the glory of God" (Rom. 3:22). Jesus is our redeemer (Rom. 3:24) and God-sent propitiation (Rom. 3:25).
Because of Jesus, we are justified (Rom. 3:24). God sent Jesus to be man's redeemer and propitiation because of God's own grace (Rom. 3:24) "to demonstrate His righteousness" (Rom. 3:25) and to justify those who put "their faith in Jesus" (Rom. 3:26).
To redeem is to repurchase.
We'll connect the dots to all of these terms and definitions in the next post, but for now, familiarization with these phrases in context of the Scripture gives the setting for understanding Christ's sacrifice and God's grace.
