In Ephesians 4:17-21, Paul admonishes Christians to forsake their former way of living, reminding them that such a way of life is not the result of “learning Christ.” While the wording (learning Christ rather than about Christ) is unusual, it is very significant. One can learn about Christ without putting their faith in Him. Genuine Christians do not put their faith in a theological philosophy but a living Savior who acted in time and space to bring redemption to His people.
