“We are of God. He who knows God hears us; he who is not of God does not hear us. By this we know the spirit of truth and the spirit of error” (1 John 4:6). 

The language of the Spirit of God rings differently in the ears of unbelievers than it does in the ears of believers. Those who have rejected God have an affinity towards things pertaining to the flesh. Any other message seems not to have any relevancy to them for their hearts are drawn in an opposite direction. When the Holy Spirit enters into one’s heart, He makes room for the truth. Only then can it become sensible and for passions to rise within him to embrace a level of teaching beyond what is commonly understood. What God has to say to us is uncommon to mankind therefore it requires more than mere common sense. In his natural state it is foolishness. But when the spirit of truth replaces the spirit of error, he will seek out teachers that will teach him things that he did not see because they cannot be seen without divine assistance.
