Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God. – 2 Corinthians 7:1

The first part of this book is meant to be a sieve to separate the chaff from the wheat. Use it on your own soul. It may be the most profitable and beneficial work you have ever done. He who looked into his accounts and found that his business was losing money was saved from bankruptcy. This may happen also to you. If, however, you discover that your heavenly business is prospering, it will be a great comfort to you. You cannot lose by honestly searching your own heart.

The second part of this book examines God's promises to His children. The promises of God not only exceed all precedent, but they also exceed all imitation. No one has been able to compete with God in the language of liberality. The promises of God are as much above all other promises as the heavens are above the earth.
