Based on the Old Testament wisdom and its many human experiences, Self-Examination and the Old Testament recreates the mindset of the main personalities dealing with self-examination. It is widely accepted that self-examination is fundamental for sustaining a healthy individual life and for peace in society. For the believer, the words and thoughts of the OT are divinely inspired, providing a spiritual foundation, and the many instances of self-examination in the Old Testament show us how to deal with delving into our own hearts and looking closely at what we find there.
