And when he comes he will convict the world in regard to sin and righteousness and condemnation. ~John 16:8
The Holy Spirit is a bit like electricity or gravity—you may not be able to understand or explain either of them but that doesn’t change their reality.
The truth is not subjective—it is objective. At the heart of the Holy Spirit’s work is this reality: God can be denied, ignored, and ridiculed; but come Judgment Day He cannot be avoided. The Holy Spirit calls us to live holy lives and provides the ability to do so and thus overcome the temptations of the world.
