This book is a collection of messages given by Brother Witness Lee, a servant of the Lord, in Taipei in 1950. It contains ten messages, covering the way for a saved person to progress in life: to be pure in heart, to remove all that covers God’s light within him, to confess his sins, to ask for God’s enlightenment, to consecrate himself to God, to deal with his conscience, to live before God, and to have a proper service in Christ. These messages have been hidden for half a century; now that they are being published, the abundance of life contained in them is once again released.
