The 500 Life-studies (500LS) app aims to help and encourage believers to become constituted with the truth in the Bible by using the Life-study of the Bible in a regular and habitual way. The Life-study of the Bible, a monumental and classic work by Witness Lee, is a book-by-book exposition of the entire Bible from the perspective of the believers’ enjoyment of Christ as life for the building up of the church as the Body of Christ. The "500" refers to the goal of reading at least 500 Life-study messages for your spiritual nourishment and growth. FEATURES: Customizable schedules: Create one or more reading schedules that can accommodate your reading capacity and time. Consider starting small to achieve better consistency. Easy access to the Life-study messages: Access your reading directly in the app via a simple reader without the need for Internet connection or via integration with ministrybooks.org (available for free or with a paid subscription). Progress visualization: Track both your overall progress and recent progress as you work toward your goals and earn milestone badges along the way.
