“Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account. Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you. Matthew 5:11–12, ESV
Christian apologetics and discernment are very serious things. It is very easy to incorporate the ways of the world into method and focus in the process. When this happens then attacks on professing Christians always come from an impure motive. This then causes the ones making the accusations to use slander, speaking evil against their target falsely.
They revile the Christian, persecuting him and his ministry using innuendo. They have no real evidence that their accusations are true. Guilt by association is their bludgeon and their usage is meant to deceive many into believing their false report. How are we to handle this? We must continue to stand firm and, using the discernment given to us by God, expose false shepherds, but foremost, it must begin with godliness.
