This book makes me so crazy. He'll say something like, "An average view of the Christian life is that it means deliverance from trouble. It is deliverance in trouble, which is very different." (August 2) And I'll say, "Yes, and Amen." Then, two paragraphs later, he'll say, "God does not give us overcoming life; He gives us life as we over come." And I'll say, "What? No." Jesus HAS (past tense) overcome the world -- John 16:33. We don't overcome the world so much as live in that belief -- 1 John 5:4&5. The work is done, we're not doing it.
On the upside, when Chambers missteps, it's just about always in one of two directions; he expects the Christian to be perfect in obedience, and he downplays Christian community. In other words, he has a bad habit of occasionally putting the Christian individual ahead of God and ahead of others! Unfortunately, what this means is that he takes the focus off of God and puts it on self, which is not what I'm looking for in a devotional.
Oswald says, "God does not give us overcoming life; He gives us life as we overcome. When the inspiration of God comes, and He says, "Arise from the dead," we have to get up; God does not lift us up." (Feb 16) But Paul says we are "raised up with Christ" (Colossians 3:1). Too often, Chambers demands that we perform; the Bible says the work has been done, and our job is to live within that fact. Oswald did not, I trust, believe that we can earn our salvation, but he still liked the idea that man can do good works for God.
But anything we can do for God, comes from God -- "the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control" (Galatians 5:22-23). While Christians should demonstrate these qualities, we cannot generate them, so when Oswald encourages people to produce these qualities, he can turn one's attention off of God and onto self.
I would definitely not recommend this book for a new Christian, or for one who struggles with legalism, or who tends to believe in the whole "earn your way to heaven" approach. And I wouldn't use it as my daily devotional, because too often it does not direct the reader to Christ but rather pushes the reader toward good behavior, a very different goal. I guess I might recommend it to someone who is solidly grounded in grace, but is looking for a push in the performance department, which is kind of why I'm sticking with it I suppose. And I do think Chambers has some good things to say. But if someone asked, I'd probably recommend something else first.
