40/40 is a resource with 40 days' Bible readings and reflections for the morning and evening aimed at helping the individual meet with God. The biblical starting point is Romans 12:2: '...be transformed by the renewing of your mind'. The author challenges readers through this guide to: 'Fight thought-disease and make your mind a healthier place.' The resource is a 40 day programme which could fit any season of the year (Lent, the New Year season, autumn or spring). The concept could work in many different ways, eg: 40 days of Bible reflection for any time, a retreat, a church-wide challenge, 40 days of reading for the journey to and from work.
