James starts off with warning people that teachers are judged more strictly than other people. Then he goes through all these analogies about how the tongue controls the body, like the bit in a horses mouth or a rudder on a ship. Then in verse 8 he says "But no one can control the tongue. It is wild and evil, full of deadly poison". He says our tongues are two-faced. We praise God with the same mouth that curses others. This is bad but it's something that we all do because we aren't perfect.
True wisdom. You can show your wisdom by living right and being humble. Verse 14 "If you are selfish and have bitter jealousy in your hearts, you have no reason to boast. Your boasting is a lie that hides the truth." This verse makes me think of a bully. They only bully others to drown out the truth inside themselves. This kind of wisdom doesn't come from God, it comes from the devil. The wisdom that God gives is, verse 17, "First, it is pure. It is also peaceful, gentle, and easy to please. This wisdom is always ready to help people who have trouble and to do good for others. This wisdom is always fair and honest." People who live right get the blessings that come from living right.
