Bill,

There is nothing mystical or impractical about following "every word" and "holding fast that which is good." I totally support that. Believing and applying scripture can seem mystical when a person is not focused on following the leading of the Holy Spirit. Or, when they are pursuing spiritual tangents where their measure of "every word" is not the balance of what scripture says, but a zealous advocation for their limited view on a particular topic. Doing that is dangerous to a person's salvation and a threat to the church when they argue for it in ways that promote division instead of harmony.
