Today's proverb is Proverbs 27. It has a lot to say about close friends, lending (surety), keeping a good name, and shrewd management of your possessions. It's 27 verses long and takes about a minute and a half to read (if you read slowly enough to try to understand it).
Proverbs that stuck out to me today (and this will change every time you read it, based mostly on the context of what's going on in your life at the time, and sometimes on the Spirit's leading):
Proverbs 27:5
"Better is open rebuke than hidden love."
This one jumped out at me because it contrasts "open rebuke" and "hidden love". Open means obvious. Hidden means, well, hidden. The two are natural opposites. Rebuke and love are not necessarily opposites, however. In fact, there are many proverbs relating to this question. A wise man should be able to accept an honest rebuke and learn from it. Defensiveness is the territory of fools. It is saying that if you openly love someone, you will openly rebuke them. This is better than hiding your love from them or for them. Hidden rebukes are for hidden love. Open rebukes are for open love. True love (between spouses, friends, significant others, etc.) should be meted out with honesty. If you can't be honest about a person's shortcomings, tell them what they are doing that is wrecking their lives or the lives of others, then your love for that person may not be as honest as you think. It is no coincidence that married couples get in the worst arguments. Brutal, blatant, open honesty is a natural attribute of love.
