Ever been to a concert where the crowd won't stop cheering until the band comes back out for an encore? Psalm 150 closes out the entire book of Psalms the same way—the word "praise" shows up 13 times in just 6 verses, the loudest "amen" in the whole Bible. But where should we sing? Why should we sing? And how should we sing—with which voices, instruments, and volume? Psalm 150 answers all three questions, showing that Jesus is worthy of praise everywhere, for who he is and what he's done, and with everything we've got: our leaders, our voices, our instruments, and our bodies.
