That's just the issue, though, Todd. Those being led astray don't have a living relationship with God (or they are being led out of one). We as their fellow believers have been placed in a position of responsibility to "shake" them a little bit to wake them up. This must be done in whatever way the Lord leads (that is, in love). But keep in mind, love could mean severity. Wigglesworth even punched some people to heal them, and the OT prophets (our examples in bringing people from error to truth by speaking the truth in love) could even be considered "cruel" in some cases -- but it was really done in love.In order to fulfill 1 Thes 5:21, everything, both good and bad must be held to the magnifying glass and exposed. That which is good will rejoice in being exposed while that which is bad will have a very negative response to the Light. One will squre with Scripture, the other will not. Then we are to hold firm to what is good while shining the light on what is bad -- think of us as walking through a dark world holding onto a light. It is not the good, solid, trustworthy things and paths that must be exposed -- they are good, trustworthy, and solid whether they are exposed or not -- it is those stumbling blocks that will harm us and must be revealed by the searchlight of the Word of God. This light must be had before one can discern the false, however, and that is why it is also so important to have truth buried deep within -- it serves as the searchlight from the Word.
