I am not sure that title expresses the subject I want to talk about here as clearly as I would like. Perhaps the following scripture will do a better job:
2Ki 20:12-17 At that time Merodach-baladan the son of Baladan, king of Babylon, sent envoys with letters and a present to Hezekiah, for he heard that Hezekiah had been sick. (13) And Hezekiah welcomed them, and he showed them all his treasure house, the silver, the gold, the spices, the precious oil, his armory, all that was found in his storehouses. There was nothing in his house or in all his realm that Hezekiah did not show them.
(14) Then Isaiah the prophet came to King Hezekiah, and said to him, “What did these men say? And from where did they come to you?” And Hezekiah said, “They have come from a far country, from Babylon.” (15) He said, “What have they seen in your house?” And Hezekiah answered, “They have seen all that is in my house; there is nothing in my storehouses that I did not show them.”
(16) Then Isaiah said to Hezekiah, “Hear the word of the LORD: (17) Behold, the days are coming, when all that is in your house, and that which your fathers have stored up till this day, shall be carried to Babylon. Nothing shall be left, says the LORD.
There it is. Understand? “They have seen all that is in my house; there is nothing in my storehouses that I did not show them.”
And, of course, as Isaiah told Hezekiah, those Babylonians would one day be back and take it all.
Have you ever been too quick to show “all that is in your house” to someone who then subsequently used this knowledge against you? I have. The fact is that wicked people like narcissists flatter us – like the false teachers who flattered the Galatians for self-promoting purposes. And it is really refreshing to find someone who seemingly and apparently genuinely is ready to be a friend.
We must be wise. We need to learn not to be so quick to “show people our treasures” as Hezekiah did. I mean, here comes these Babylonians because, they claimed, they had heard that Hezekiah had been sick. They brought gifts from the Babylonian king and perhaps the ancient version of get-well cards. Hezekiah, like us, really appreciated this kindness and his response was to show them everything. To share his life with them. Mistake.
Now, the truth is that there is no sure-fire answer to the question – “how do we know someone’s real motives?” “How can we know if someone is trustworthy?” But one bit of wisdom is, don’t be too quick to share your life. An evil person will one day use the “treasures” you have shown them against you. As Proverbs says, such a person will one day “reveal” the things they now know about you as ammunition for their own profit.
Pro 11:13 Whoever goes about slandering reveals secrets, but he who is trustworthy in spirit keeps a thing covered.
