"Test everything. Hold onto the good."
1 Thessalonians 5:21
A man who ate locusts and dressed in wild skins; a prostitute; a donkey given to speaking - these are some of the beings God chose to reveal Himself through as mentioned in His Word. So why do we have such a problem accepting God's revelation from people whose culture or social standing may be offensive to us?
You may be Conservative with a dislike for loud prayers; you may be Pentecostal with an aversion to quiet prayers; you may be well dressed with an objection of people who smell - don't let that disqualify you from hearing God. God didn't come to earth in the form of an Armani-clad motivational speaker. He chose to come as a carpenter from Nazareth - a hillbilly with a broad accent that some people would have shown contempt for.
There can be great grains of gold in the seas of sand. We can find something from God if we test everything and hold onto the good that remains. We can hold up someone's words against the Bible and hold onto those things that comply. Just don't be so open minded that your brain falls out! Let God speak however He chooses to and you'll be surprised at the great pearls that you will discover.
