This book is serves as a solid introduction to the Five Ways of St. Thomas Aquinas. I'm not a philosopher or had any real training in philosophy, so rereading each proof and researching other ways of understanding each proof was a must for me. Because this was my first real undertaking into understanding philosophy, the book has opened up an entirely new way of thinking about who God is for me, and that's incredibly exciting. Aquinas gives us today new, but actually very old ways, of understanding who God is, or has Aquinas often expressed, Being Itself. I'll leave you with this quote towards the end that encompasses the importance of working to understand God in these ways.
"So, love is the reason, but not the cause, why God creates. To love is to will something good towards that person. And in giving us existence, life, and intelligence, God has given human beings good things-- wonderful things. It is only by existence that we can enjoy the beauty of a sunset, the company of a friend, the laughter of a young child, and falling in love with another person. Thus, it is only by existence that we can participate in the goodness of being, which is to participate, in our own limited way, in God's wondrous life." Amen
