Even within the thousands of professing “Christian” churches and sects, there is almost no real understanding of God’s true plan and purpose for mankind. A large part of the reason for this is because the knowledge of God’s Holy Days, called Sabbaths and holy convocations in His word, has been lost—indeed, they are not even kept, or kept properly when they are! Pastor John Strain explains five points about the meaning behind God’s commanded assemblies and why true Christians should observe them, as well as what happens to a godly nation when they fail to follow God’s instructions about how and when to assemble together to worship Him.
