Paul tells you when you are filled with God's Spirit you are empowered to speak to each other with the soulful words of pious songs, hymns, and spiritual songs. You know where you find those? The Psalms that speak of His joy. The Wisdom books that tell His story, strength, and glory. The Prophets that promise the riches of heaven to those that follow Him. Those pious songs are filled with the joy of following God. There are no funeral dirges in those songs, but rather hymns of praise to Him.
