Honest to God is a well-written book that contains many important truths to keep in mind. On more than one occasion tears welled up in my eyes as the author, Josh Weidmann, drew my attention to the amazing grace of God. I was especially encouraged by reading the Canyon's Edge parable in chapter 11.
I disagree with a few minor details. For example, on page 32 (kindle Loc 399), Weidmann claims that God cursed Adam and Eve. Although God's punishment upon them was curse-like, God specifically claims to curse only Satan and the ground (Gen. 3:15 & 17), not Adam and Eve. Cain was the first human to be cursed (Gen. 4:11).
Additionally, on page 72 (Kindle Loc 936), Weidmann seems to suggest that the recognition that one is "not good enough" necessitates riding "the woe-is-me train all the way to I'm-a-Loserville." I believe, however, that truly no one is good enough, yet this makes God's grace all the more amazing! I don't cry "woe-is-me" when I recognize that I'm not good enough; rather, I praise God for His redeeming grace and mercy in causing me to be born again!
On page 108 (Kindle Loc 1400), Weidmann claims that God's love is the most important of His attributes, "without which [our] picture of who God is will always be incomplete." Although I believe God's love is without a doubt important, I don't believe it's true to say that His love is the most important of His attributes. I believe all His attributes—including His holiness and sovereignty—are equal in importance, and therefore every one of His attributes is necessary to have a complete picture of who God is.
Finally, I've never been comfortable with the idea that we—God's creation—allow and/or grant God permission to do things. Yet Weidmann says that we allow God to bring us healing and wholeness when we open our heart to Him (pg. 137; Kindle Loc 1792), and that we grant Him "control to teach, guide, comfort, and empower [our] spiritual journey" (pg. 141; Kindle Loc 1849). If God has chosen us before the foundation of the world to make us holy and blameless (Eph. 1:4), and if God has predestined us to be conformed into the image of His Son (Rom. 8:29), then I don't believe He needs our permission to heal and make us whole, or to take control of our spiritual journey.
Over all, I would recommend reading this book. The issue of honesty truly is of utmost importance.
