Proverbs 25:27 It is not good to eat much honey: so for men to search their own glory is not glory.
28 He that hath no rule over his own spirit is like a city that is broken down, and without walls.
We see two good lessons here, the first is that when we brag about ourselves and promote our own agendas people will get sick and tired of us. Just like the analogy used of eating too much honey making one sick. Next we see if someone has no control over their emotions and passions they are opening themselves up for all kinds of sin in their life. This is like a city without any walls that is being attacked there is no hope for it. From these verses we should learn that if we just live our life in a way that shows the love of God we do not have to say a word and we need to stay strong enough in the word of God that we can control our spirit in a Godly way.
