Ben, our very own Death is Gain, sent me this book last month and I am finally getting around to reading it. To be honest I had a hard time putting it down even to write this. Slave, by John MacArthur, is an amazing look at what it truly means to have Jesus as the Master of your life. Of course if He is the Master, that necessarily makes His followers slaves. This book looks at all of that and it also takes time to look at some of the history of the Reformation. Please take the time to check out this book and find out what your true identity in Christ is today! There is also a study guide that allows slave to be used in a small group setting. If you are involved in some sort of shepherd group this would be a great book to go through together! Below are some links to where you can pick up your copy! Hope that it blesses you as it has me, Virg.
Grace to you
Holman Christian Standard Bible (HCSB)
I am using a human analogy because of the weakness of your flesh. For just as you offered the parts of yourselves as slaves to moral impurity, and to greater and greater lawlessness, so now offer them as slaves to righteousness, which results in sanctification.
