The next sermon in our summer series is by John MacArthur from Shepherd's Conference 2018 at Grace Community Church. In this message, he addresses the need to not only preach the gospel, but to also guard it with courage and boldness in a world full of false doctrines that try to add works to salvation. True salvation is only by grace alone through faith alone in Christ alone.For more information on Shepherd's Conference or to hear more messages from the conference, visit https://shepherdscon...
