Nowhere is this more clear than in the recent sensation "The Shack", a book that speaks against God. Now if I were God and someone wanted to write a book blaspheming me I'd use my power to ensure that the book was terrifically unpopular and that nobody read it. But does God do that? Nope. He puts it into the hand of everyone and permits it to go on to be a runaway best seller. That the book goes on to sell a million copies and the author and publisher get rich. And it's at this point that God punishes them.
As He Himself said, "But they that will be rich fall into temptation and a snare, and into many foolish and hurtful lusts, which drown men in destruction and perdition. For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows. But thou, O man of God, flee these things; and follow after righteousness, godliness, faith, love, patience, meekness." (1 Tim 6:9-11)
