James McDonald has a clear and very helpful post on understanding five of the most common distortions of the Gospel that we see in churches today.
Phil Johnson’s Weekly Dose of Spurgeon has posted a great excerpt.
He who does not hate the false does not love the true; and he to whom it is all the same whether it be God’s word or man’s, is himself unrenewed at heart. Oh, if some of you were like your fathers you would not have tolerated in this age the wagon loads of trash under which the gospel has been of late buried by ministers of your own choosing. You would have hurled out of your pulpits the men who are enemies to the fundamental doctrines of your churches, and yet are crafty enough to become your pastors and undermine the faith of a fickle and superficial generation.
