Psalms are kind of like really special songs that people wrote a long, long time ago to talk to God and say how much they loved Him. They are part of a really important book in the Bible called the Book of Psalms that has lots of different songs and poems in it.
Some of the psalms talk about happy things, like how beautiful the world is and how grateful people are for everything God does for them. Other psalms talk about sad things, like when someone is sick or lonely or just feeling really upset. But no matter what kind of psalm it is, they all come from people who believe that God is listening to them and will help them feel better.
Lots of people still read and sing psalms today, because they help remind us of how much God loves us and how we can talk to Him whenever we need to. They're a really special way for people to connect with their faith and feel closer to God.
