Along with having maybe the coolest accent of all time, Dr. Sinclair Ferguson is a once-in-a-generation preacher.
If you haven’t heard him before, you are absolutely missing out. His preaching is both theologically rich and full of pastoral wisdom. The website below helpfully organizes many of his sermons by Scripture/topic. I will often listen to one of these as part of my own sermon prep. Adam Jones had Dr. Ferguson over to his house for dinner on several occasions when they lived in Orlando, and attests to his genuine love for Jesus and the church. Being Scottish, he is part of the history of Presbyterianism that traces its roots back to John Knox. Search through the catalog, find a sermon title that interests you, and enjoy!
