OSL is a highly effective and proven system of discipleship that has been written, tested, and refined — time and again — for over 30 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 six 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.

Level 1 is four weeks plus the orientation class. The rest of the levels are six weeks, plus the orientation class. Then Level 6 goes back to four weeks, plus orientation. Each student is assigned a coach and placed into a small group for the purpose of encouragement and accountability. The classes run between two to three hours, depending on the level.

      •   Infilling of the Holy Spirit
      •   Our covenant with God
      •   Reconciling God's Sovereignty with His promises

Level 3 takes us through a study of the Word of God from various angles: Its origin, how it came to us, insights about translations and five ways to receive from it. Level 3 also takes us through a study of how to use the Word of God as our primary weapon in the spirit realm.
