Most bibles today have some form of headings. In the AMP version of our text it says Unbelief and Its Consequences. I think most translations have something similar.
While this section clearly is a warning to unbelievers it is also a WAKE UP CALL to the complacent church. For far to long the church has sat back and let the world dictate what would happen, we would loose school prayer, make murder (abortions) and LGBTQ normal, and denounce God from national platforms just to name a few. The church grumbles and mumbles but has for the most part remained silent.
This morning I thought I would do something different and offer you a sermon from Pastor John MacArthur, whom you may knows church is in a battle with the state of CA over the constitutional right to assemble. I firmly believe this and much of what we see in America is because of our Churches Silenced Conscience.
