In Ephesians 4, the apostle Paul described the characteristic walk of worldly people. He refers to them here as “the rest of the Gentiles” (17). For the Jew, Gentiles were considered to be unclean (cf. Acts 10:16). God declared that under the new covenant the important thing was not your nationality, but whether you have faith in Jesus Christ. “For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God” (Romans 2:28-29). Therefore Paul’s reference here to the Gentiles is not to the physical Gentile but the man who has not been washed or sanctified before Him.
His description of them? They were futile in their thinking, with darkened understanding. They had given themselves over to lewdness, uncleanness and greediness.
This type of behavior is antithetical to being a Christian, an inward Jew. This is why in verse 20 of Ephesians 4, Paul wrote, “But you have not so learned Christ, if indeed you have heard Him and have been taught by Him, as the truth is in Jesus.” Christ teaches us that when we are separated to God through faith, we are to live our lives as a “new man which was created according to God, in true righteousness and holiness” (24). Learn from Him!
