Do Christians have to follow a prescribed religious ritual the way people in religion do?
No. Set free believers do not have a prescribed ritual to follow, unlike the Jew or person in religion who must follow the ritual. They are individually accountable to God and simply in tune with God, doing what He leads them to do.
Les teaches that the Jew or the person in a religion has to follow the ritual, but the set free believer does not have a prescribed ritual. Instead, the believer is individually accountable to God and God alone, which is logical, practical service. The believer is simply in tune with God and does what He leads them to do. Les also notes the exhortation not to be conformed to this world, explaining that “world” is usually either “cosmos” or “ion,” meaning age, so we are not to be molded by the god of this age or this world.
