God’s Plumb Line is designed to help us think with what Paul called “the mind of Christ” (1 Corinthians 2:16) – that is, thinking that is shaped by the character of God and the ways of God. This kind of thinking is Spirit-shaped thinking (1 Corinthians 2:7-16). The Apostle Paul identified this kind of thinking as the “renewing of the mind.” It is the means by which our lives are transformed (Romans 12:2). In addition, it positions us to “discern what is the will of God – what is good and acceptable and perfect” (Romans 12:2).
Until we learn to think with the mind of Christ, we naturally function out of the way the world trained us to think. Our thinking, values, and positions of moral issues reflect the ways of the world rather than the ways of God.
The book identifies seven markers in God’s plumb line, beginning with the character of God revealed to Moses at Mt. Sinai (Exodus 34:6-7) then moving to the life, ministry, and teachings of Jesus. Each marker grows out of and aligns with the previous one. These seven markers help us align our hearts with the heart of God, our minds with the mind of Christ, and our lives with the ways of the Kingdom.
