Some of the chapters in the book of Psalms are centered either
on David asking God to destroy his enemies, or they speak of
past / present / future events of the Hebrews.

This list removes those, and centers on the essence, worship and praise of God.

I'm sure that each one was created from the person's heart, which I
believe is one of the most important aspects of prayer & worship, since
that is where true love for God and His Son originate and reside.

And therefore, in your own prayers, don't worry about "creating"
eloquent-sounding verses / rhymes etc....

....both God and Jesus would rather hear straight from your heart.
