One of my favorite prayer books is, The Valley of Vision: A Collection of Puritan Prayers and Devotions, edited by Arthur Bennett. These very old prayers capture different aspects of spirituality, including many that I may not regularly see in my modern context. They provide a different perspective, and challenge me to a deeper, thoughtful, and more well-rounded faith. While I love the spirit of contemporaneous prayer, I also love the theological discipline of a written prayer. As with real life, sometimes it is better to write something down carefully, in order to best capture one's true thoughts.
Here is "A Convert's First Prayer," from The Valley of Vision. I have only altered some of the King James English.
I could never have sought my happiness in your love, unless you had first loved me.
Your Spirit has encouraged me by grace to seek you,
has made known to me your reconciliation in Jesus,
has taught me to believe it,
has helped me to take you for my God and portion.
