God's Pursuit of Man by A. W. Tozer
God's Pursuit of Man is the prequel to another book that Tozer wrote titled The Pursuit of God. I highly suggest you read as much Tozer as you possibly can, but this one book is truly amazing. Start with this one. It will help you understand why you need to make sure you are giving your everything to God and your faith and help you analyze whether you are doing just that or are you just giving a half version of what your faith can be.
I know that Tozer can be a little intimidating and trust me, I was a little concerned as to whether I would gain anything or even understand his teachings and writing since I am not a minister or biblical scholar, but I came to find out while reading this, that yes, I can gain a TON and further my walk with God so much more now that I have introduced Tozer's writing into my life. He has a way of being truly convicting and extremely educating all at the same time, but not in a way that feels like he is talking down to you. It feels like he really wants to help you get to know God more and find a closer relationship with Him.
I highly, HIGHLY suggest that you start reading Tozer's writing if you want to deepen your walk with God. You will never know how great his teachings are until you pick this book up and read it for yourself. I know that I can't get enough of Tozer now!
