SINGING
According to scriptures such as Isaiah 42:10, Psalms 96:1-2 and 98:1 of the same book, the Spirit of love admonishes us to sing a new song to the Lord because the revelation and understanding of God's word given to His people increases. And as the revelation and understanding of His word increases in you, new songs are birthed in you through Him. The word doesn't change. But the more you open your heart to His teaching and training ministry, the more you would know and see; the more revelation knowledge will be granted you.
