Blessed is the one who obeys the law of the Lord. He doesn't follow the advice of evil people. He doesn't make a habit of doing what sinners do. He doesn't join those who make fun of the LORD and his law.
Instead, he takes delight in the law of the Lord. He thinks about his law day and night.
He is like a tree that is planted near a stream of water. It always bears its fruit at the right time. Its leaves don't dry up. Everything godly people do turns out well.
Sinful people are not like that at all. They are like straw that the wind blows away.
When the LORD judges them, their life will come to an end. Sinners won't have any place among those who are godly.
The LORD watches over the lives of those who are godly. But the lives of sinful people will lead to their death.
