While godly righteousness is open-ended, allowing room for growth, human righteousness is self-limiting because of its self-centered mindset, smugly satisfied with its accomplishments. The attainment of godly righteousness demands humility, a readiness to admit shortcomings, a yieldedness to correction, and a willingness to be refashioned. Before one can become a good example to others (serving as an improver), he must develop the humble attitude of being willing to be shaped by God's Holy Spirit, realizing shortcomings, and continually hungering and thirsting for righteousness. Achieving perfection through human devices (trusting human sensory equipment and reason for deciding standards rather than relying upon God) will severely limit spiritual growth.
