Church Hymns are beautiful melodies

At the easter solemn mass, I was singing hymns in all gusto. I realized that these hymns are poignant and melodious. Why were these hymns not dull. Something that was forced out of our mouths to give praises to god? Why were these hymns not just poetry that are incompatible with their melody? No. But they are rich in striking a chord with our souls and allowing us to exalt god. I then realized what God did. He reserved the best of the melodies for himself.
