The book of Hebrews is full of warnings, specifically written to Hebrew believers of the first century, who were being persecuted and compelled by Judaizers to return to the dead Old Covenant system. But this is a timeless warning, which is relevant to us today. The sin of apostasy (or of falling away from Christ and renouncing our profession of faith in Christ) is rampant in our day, in America, There is very little to no persecution and fear for those who are Christians in America. But what there is, is far worse, there is ease, comfort, prosperity, and love of the world. These sins plague the church today. It is as if Satan has said, I won't persecute American Christians, I'll just draw them into the world! I will just allure them back to me and back into the world. And in doing so, I will make them adversaries against Christ.
