The circle helps you identify the significant events of your life in a way that enables you to move deeper in the direction of God's will. "Kairos" moments occur when God breaks into your circumstances when an event that transforms you. Those moments are God-given opportunities to enter into the ongoing process of learning more about how to live for Him. God hopes you will respond to kairos moments by repenting and believing. The first half of the circle represents the steps involved in repenting (honestly observe your thoughts and feelings about what happened, reflect on why you reacted to the event as you did, and discuss your observations with trustworthy friends who will pray with you). The second half of the circle represents the steps involved in believing that inner change is possible for you (make a plan to lead to change, have someone hold you accountable to that plan, and put the plan into action). Just like a circle, your life is a series of loops held together by time. Each time you go around a loop, you can seek to grow more in spiritual maturity.
You can rediscover the rhythm of life your Creator, God, intended for you in the principles of the semi-circle. The semi-circle illustrates how there is an important balance between work and rest. Remember that you're a human being, not a human doing. Realize that in order to be productive in your work, you must make enough time to rest. Understand that, just like a pendulum swinging back and forth, you should abide (rest) in Christ, go forth to bear fruit, then allow yourself to be pruned back and enter another time of abiding. Realize that, just as in nature, growth must happen in your life you can produce fruit - and growth comes only from abiding.
