Then electricity becomes truth to him and he believes in the operation of a light switch. He who knows to flip the switch and does not do it, has no one to blame but himself if he stumps his toe. We are sanctified by the truth that is given to us by the Holy Spirit. The truth continues this process of sanctification through the Holy Spirit. The emphasis is on the Holy Spirit, who teaches truth, and his teaching will set you free.
Man is set free by knowledge.
We've come out of the dark ages of outhouses, and meat houses, through the knowledge of plumbing and refrigeration. We were set free from these primitive ways of life in America. But, just like electricity, there are those in our world who know nothing about plumbing or refrigeration. They are not set free. To him that knoweth to do good and does it not, to him it is sin.
