Exposing John MacArthur’s Leaky Dispensationalism. Here, we look at the “leaky dispensationalism“ of John MacArthur (part 2). What is a free grace understanding of the gospel and what is dispensationalism and how are these two subjects related? We demonstrate that if someone is compromised on the issue of dispensationalism it often has a negative impact on their understanding and presentation of the gospel. Very few ministries either understand this reality or will ever connect the dots for people in this regard. However, here, we attempt to make this connection for you.
