NOTES for Eph 6:10-24
From the theme of social relations Paul moves to the theme of Christian ministry and its place in society. He immediately proclaims that Christians do not struggle against people, even if those people are in power. Following Jewish usage, he calls people "flesh and blood." The aim of their struggle is the spiritual forces that determine the condition of the fallen world, which he calls "rulers," "authorities," and "controllers of this present darkness" ("world rulers of the darkness of this age"), connecting with them "the breath of evil that is under heaven" ("spiritual hosts of wickedness under heaven," v. 12). The goal of Christians, as we can see, is not the seizure of power or social change as such, but the lessening of the influence of those forces of evil which, while acting mainly through people, are not themselves human, using the human person only as an instrument. Of course, a person can become such an instrument only by giving consent to it.
In saying this, the apostle was probably warning those who were carried away by ideas of religious-political messianism, which were widespread in those days in synagogue and near-synagogue circles. And any struggle for power in general, if it becomes an end in itself, by no means lessens the measure of evil in the world; it gives the spirits of darkness the broadest scope for their activity. Only the Kingdom entering the world can lessen that measure, and therefore the Christian's main task is witness to the Kingdom and to salvation, as well as to the One who brought it into the world. But for this witness to be adequate, the witness needs faithfulness ("truth") and righteousness, without which one cannot share in the Kingdom (vv. 14-15). And the main weapons of the witness in resisting the evil in which the world lies are trust in God ("faith"), righteousness, which is the best witness to the Kingdom, and the Torah, the word of God, which makes it possible to distinguish good from evil and to make the right choice in the difficult situations in which the witness sooner or later will find himself (vv. 14-17). On that choice, in the end, will depend not only the fate of those to whom he bears witness, but also his own salvation.
