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.

Current Sessions

Each level builds a biblical foundation for the next level. 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.

Level One

Level 1 is where many people have the most exciting and life- changing experience. In this level you will discover, more deeply than ever before, how much Jesus really loves... and how much He wants to be with you for the rest of His life... forever! 

Key Teachings Include:
      •   The Love of God
      •   The Believer's Righteousness In Christ

Level Two

Level 2 takes it up a notch with some of the most treasured studies in OSL. We will let Jesus teach us— in much detail— His three steps to a solid and fruitful life in the kingdom of God and learn to regularly receive the fullness of God's Spirit.

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

Level Three

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.

Key Teachings Include:
     • The Power of God's Word Against the Enemy
     • God's Word and How It Produces Results In Our Lives
     • How To Study the Word

Level 4 will spend time studying the great authority we have on the earth through Jesus and how to use it. We will learn how to be led by the Holy Spirit and to minister to people through the manifestations of the Holy Spirit.

Key Teachings Include:
     • Recognizing the Believers’ Authority
     • Being led and empowered by the Holy Spirit
     • Effective Prayer 

Level Five

Level 5 will focus entirely on your ministry to others. In this level we will study many of the keys and principles regarding ministry from the Word of God. We will study how to relate to Him in ministry, how to relate to our overseers and peers, and how to purify the motives of our heart.

Key Teachings Include:
      • Unlocking Keys To Effective Ministry For The Kingdom Of God 

Level Six

For those who said five levels isn't enough, we added one more. Level 6 will focus on the unstoppable Spirit-filled church.
