Andrew Strom in one of his newsletters noted that Jesus told His disciples, "If a house does not welcome you, shake the dust off your feet." This is actually in three of the Gospels.
Matthew 10:14
And whoever will not receive you nor hear your words, when you depart from that house or city, shake off the dust from your feet.
Mark 6:11
And whoever will not receive you nor hear you, when you depart from there, shake off the dust under your feet as a testimony against them. Assuredly, I say to you, it will be more tolerable for Sodom and Gomorrah in the day of judgment than for that city!
Luke 9:5
And whoever will not receive you, when you go out of that city, shake off the very dust from your feet as a testimony against them.
Maybe Christ simply did not want the disciples to burden themselves with the goats, as it would be wasted energy. To better explain it, you could draw in a goat with great performances and clever intellect, but when the substance of the Gospel actually comes around, the parts that prick the conscience and shine a light in their dark corners, will they listen? If not, and the Holy Spirit cannot seem to reach them, how could we?
Perhaps entertainment hinders the work of conviction, because they are not spurred to repentence the way they could be, but are only entertained. Do we risk the straight and narrow being lost on them when we do this? Just the opposite of doing what the Spirit won't, are we [i]substituting[/i] the good work of the Holy Spirit in this case? The move of the Holy Spirit will bring both works into perspective, driving out the goats to make room for the sheep.
