Was John MacArthur and Grace Community Church sinning by gathering?

A lot of Christians have been watching the unfolding news headlines of what is happening in California and Pastor John MacArthur's Grace Community Church (GCC). Many are asking some great questions, like, are John MacArthur, the elders of GCC, and the members of GCC sinning by meeting indoors in person, and thereby disobeying the governor’s order? Why couldn't they just try to meet in other ways? And what about the lawsuit that GCC is bringing against the state of California? Is that biblical? Michelle and Amy discuss what the Bible has to say about this topic.
