I just watched this video on FB wherein the late Ian Paisley mentions the introduction of no-fault divorce into Britain. While I was not the biggest fan of him when he was alive, I consider his warning on this issue to have been prescient.
I have a lot of Ian Paisley preaching on SA. It is an encouragement for me to hear him. That being said, I think Ian Paisley's preaching style is more like a rallying speech than an expository preaching, which should be the main characteristic of a preacher. Dr. Paisley could be a good substitute for evangelist Billy Graham. He is a brilliant politician as well. No one is bold as him to confront the apostasy and sins of his days. And by the way, I'm a member of his denomination.
To response to your comment on his attack on divorce law, I have been thinking many times about the importance of Gospel witnessing, the main function of the church. Obviously, Christians should lament and response politically to this sin. But I think a revival is the best remedy in changing the heart and mind of sinners.
