May I encourage you to pick up a few copies of this book? One, for your personal reading; and the others because I’m sure you’ll want to pass this one along as well…
“The history of the Christian Church is punctuated by a number of books which can best be described as ‘small, but seminal’. 
The category includes Martin Luther’s Freedom of the Christian Man, John Calvin’s Golden Booklet of the Christian Life, Richard Sibbes’ The Bruised Reed, Henry Scougal’s The Life of God in the Soul of Man and a number of others. Capable of being read in an hour or so they contain principles, insights and spiritual wisdom to last a lifetime. William Still’s Towards Spiritual Maturity can be included in this category. It contains the distilled essence of his ministry. Like a number of books by other authors in the same category, it expresses principles discovered early on in his ministry and test-driven throughout it. The burden of these pages was expounded in his public ministry of the Word, applied in his private counseling and became part of the heart-beat of his congregation’s life. Under God, the teaching in these pages on what Mr Still often referred to as ‘the three dimensions of evil’, while by no means unique, came alive and brought both illumination and spiritual help to several generations of Christians. The same will surely be true of the present generation, and for some this little book may even prove to be a life-saver and a restoration of Christian stability and sanity.”
….It is not wrong to regard the death of Christ as the supreme example of sacrificial love; but his death is more than that. Failure to see this accounts for the spiritual listlessness of many who hold a mere exemplary view as the whole truth. For the death of Christ is no mere display of love in action. It is the putting away of the sins which set up a barrier to the very possibility of love between God and man. It is not only an exhibition, but a removal. Indeed it is more a removal than an exhibition, for it is one thing to show sinners what they ought to do, and quite another to do it for them when they are helpless to do anything for themselves. We need not only pictures, but power, not only diagrams, but dynamics. This we have in the death of Christ, which is nothing if not an actual, factual, objective putting away of our sins.”
