I have recently uploaded to the Web some older material that is out of print which I find to be very edifying and which is helpful for spiritual growth.
The first is New Testament Living, The Inwardness of the Christian Life by Norman B. Harrison. What clarity of thought breaks upon my understanding about how the identification truths of the Cross and Resurrection are brought to bear on our hearts by the Holy Spirit so that our behavior and conduct are a true reflection of our inner-man in Christ. You can read or download it here:

The other is a commentary on the book of Galatians by William Kelly. Paul's rebuking the Galatian church for falling for the "other gospel" of mixing law and grace is far stronger than his rebuke of the church at Corinth. This study is also conducive to Christian growth. The law (of Moses) is not able to give us power to keep it and of course we are not perfectly able to keep it by just will-power. The problem is not with the law, it is good. The problem is with the weakness and inability of the flesh to please God. Besides, the law (of Moses) has been superseded by the indwelling Christ. We now trust and rely on the indwelling Christ to live his life through us as we abide and yield to Him. Now our responsibility is to believe, abide, reckon, present, yield, and offer ourselves unto God as alive from the dead. We don't rely on our own (apart from Him) goodness because it ain't all that good. Anyway, have a look at this one too. The beginning of the book presents the entire book of Galatians in William Kelly's translation. The commentary comes afterward.

Another treatment on the book of Galatians by Norman B. Harrison is "His Side versus Our Side". It too is quite good.

I just want to get straight here that the law is good and we aren't supposed to practice evil or live without conscience before God. The problem was with man's inability to keep the law. Now we live by grace by the indwelling Christ and do not look upon the law as either the means or a means of obtaining sanctification.
