Whose message?

Peter is on the roof, probably enjoying the coolness and snoozing as he waits for lunch, when the sheet comes down from the sky, filled with all types of unclean animals. A voice asks him to choose his dinner from amongst them, but Peter knows that God had forbidden His people from eating such things, so he is ready with a swift and confident refusal to comply. Test complete, right? But the voice asserts that Peter is not to call unclean what God has called clean.

Maybe he could have written it off as a weird dream if it had just happened once, but it happens three times, and Peter has a thing with the number three.

So after the third time, Peter, an apostle who had walked closely with Jesus, who has been visited by the Holy Spirit, who will write words inspired by God himself...is really confused.

How can he tell who sent this vision, and why? Is it a trial from God to prove Peter's steadfastness one more time, or is it a temptation from Satan, who may have seen Peter inhale a little more deeply as he walked by a Gentile dwelling in which pork was being prepared?

Is this a legitimate extension of freedom (there is precedent for this [Matt. 12:1-12]), or the chance to prove that following God was more important to him than following his baser instincts (precedent exists for that, too [Matt. 26:69-75])?

Would Peter have ever figured it out if visitors hadn't shown up that very afternoon and made it clear that vision wasn't mainly about food, after all?

Through my whole life, no matter what thoughts and feelings swirl in my head, may I always receive such clear guidance when I am meant to move on them, and may I be willing to sit on confusion on the roof forever if such clarity does not present itself. (God grant me the grace and wisdom for both.)
