OPERATION: SOLID LIVES (OSL) is a highly effective and proven system of discipleship that has been written, tested, and refined — time and again — for over 20 years, to maximize its ability to impact an individual and to accommodate masses of genuinely hungry believers. Virtually anyone with a good attitude and a willing heart can participate in and graduate from OSL, including those with limitations or disabilities. It is designed with five levels which build — one upon another — to lay a solid biblical foundation. All levels include powerful audio teachings, daily Bible reading and response journaling, Bible memorization and other key disciplines. Thousands of people have begun this process, and the testimonies are amazing.
