Osteen doesn’t preach grace. He preaches a prosperity gospel using scripture in a corrupted manner.
Was that in today's devotional? Yesterday's? In which of these devotionals does he do that? You can't say because his devotionals don't contain what you falsely accuse him of.
Besides, that misses the point of the issue here. Regardless of personal preference, good-faith devotionals are welcomed on FR and this in one of them. If you don't like it, you don't have to read it, just move on.
