Pastor Jeff Dowell does a deep dive into the topic of the 7th day Sabbath in the Bible called "Facing the Critics". Lots of videos in this series.
Pastor Jeff has done a 4 part series on the second coming of Christ. This is the great hope of all Christians all around the world. But unfortunately modern interpretations of the Bible in regards to the second coming are not based on the Bible. In parts 1 through 3 Pastor Jeff dissects the modern false teachings on the second coming, and in part 4 he explains what the Bible does teach on the subject.
In this 3 part video series Pastor Jeff is answering the questions that anti-Trinitarians are rising in the church about the nature of the Holy Spirit. Please note these videos are audio and slides only.
