Continuing the discussion of the ministry of a witness, Paul especially emphasizes the need to move the listeners' focus away from the witness's personality and toward God and Christ, so that no one would attribute the power of God and the breath of the Kingdom to the witness himself as a human being (v. 7). It is from this point of view that the apostle considers the persecutions and afflictions that often fell both on him and on his companions (vv. 8-9). Of course, the witness of a true witness would not become false or less significant even if he were surrounded by honor and respect. But in that case there would always be a danger that the minds and hearts of the listeners were being influenced not so much by the witness itself as by additional factors: the force of the witness's personality, the general respect shown to him, and the pressure of public opinion.
Of course, this influence is not dangerous in itself, at least as long as it directs a person in the right direction. But under such conditions a certain kind of self-deception is always possible, when a person considers himself, at times quite sincerely, a Christian not because he seeks the Kingdom and is ready to follow Christ, but because he has fallen under the spell of a famous, respected, and perhaps truly outstanding spiritual leader. It is always psychologically harder to follow a persecuted or at least unpopular preacher, but in that case the chances are noticeably higher that the follower shares the values and convictions of his leader, rather than merely yielding to his charm, though of course there are exceptions.
But another point is important as well: witness to the Kingdom there and then, where and when there appears to be no hope not only for the triumph of the ideas the preacher defends, but even simply for a favorable outcome (vv. 10-12). In such a situation the reality of the Kingdom is either experienced with utmost clarity or, if it remains only an abstraction for the listeners, is not experienced at all. It is no accident that Paul says the death overtaking the apostle and his companions turns into the fullness of the life of Christ and the Kingdom for those to whom they testify, including the Christians of Corinth (v. 12). Nothing is so convincing as the triumph of the Kingdom revealed in the life of a persecuted witness (vv. 13-15). That is what keeps Paul from losing heart: he truly experiences this triumph during persecutions, seeing the Kingdom expand and include ever new inhabitants (vv. 16-18).
