Right in the middle of the Bible we find 150 songs that God gave to David, and the first one is very definitely about the difference between good and bad.
Psalm 1
1. How blessed is the man who does not walk in the counsel of the wicked, Nor stand in the path of sinners, Nor sit in the seat of scoffers!These lines were written almost 3 thousand years ago, so the language and setting is a bit different from what we use in the city today. They were written about people living in the country, so there are references to country things. Neither were the thought police around to tell us that we must not say that there are good people are that there are bad ones.
2. But his delight is in the law of the LORD, And in His law he meditates day and night.
3. He will be like a tree {firmly} planted by streams of water, Which yields its fruit in its season And its leaf does not wither; And in whatever he does, he prospers.
4. The wicked are not so, But they are like chaff which the wind drives away.
5. Therefore the wicked will not stand in the judgment, Nor sinners in the assembly of the righteous.
6. For the LORD knows the way of the righteous, But the way of the wicked will perish.
The word blessed means happy or having good things happen to you, and the word man as used here means people, human people. And of course the writer is talking about things from God’s point of view, for Jesus said that God is the only one who is really good, and He is also the One who does good for the people who please Him.
Pleasing God then means not walking in the bad way, not standing in the bad way nor sitting with those who make fun of the good way. God will send good things to that person, for He is able to control all the circumstances.
Gladly hearing and thinking about God’s word -- what He has said – is what we should be doing instead of those bad things. The good person is now compared to a tree growing in the best well-watered field which is always loaded with lush fruit, a rural picture of prosperity and blessing.
However those people who are not blessed, who are not pleasing God get none of these good things. They are compared to the worthless residue of the wheat plant after the grain is threshed out of it, they are blown away. And the final part warns us that God Himself sees and knows all kinds of people and that He will surely bless the good and cut off the wicked.
