I find him pretty solid usually, but I did have an issue with one of his sermons. The sermon in question was to a group of college age kids or maybe high school, and he went on about how many professing Christians are not saved. I agree, but he started talking about how people who looked and smelled like the world, and who listened to secular music and tv were in trouble. He also talked how women and men both dressed immodestly. I think there is a certain amount of discernment we need to have in our media intake and dress, but being told that I am going to hell because I like to wear skinny jeans and a v neck really seems pretty legalistic, and not at all like his usual messages.
The thing I like about him is he talks a lot about centering your joy and peace on what Christ did at the cross, not how much you can do for God and how much you succeed. That's an issue I've always struggled with it and I feel like God has used some of his sermons to help me to understand that a little better.
