John Nelson Darby emphasizes the two foundational principles of divine life found in Psalms 16 and 17: trust in God and the consciousness of righteousness. He explains that while the Psalms express the struggles of believers, they do not fully reveal the foundation of God's righteousness as understood in the New Testament. Darby highlights that Christ exemplified perfect trust and integrity, and through Him, believers can find assurance of their standing in divine righteousness. He contrasts the Old Testament understanding of mercy and righteousness with the New Testament revelation of accomplished righteousness through Christ, which brings peace and hope to believers. Ultimately, he encourages Christians to embrace their identity as children of God, living in the certainty of their relationship with Him.

A.B. Simpson emphasizes that while no one is perfect, it is essential to strive for righteousness through Christ, who offers a divine righteousness that transforms our very being. He explains that this righteousness is not just about forgiveness but involves a deep union with Christ, aligning our thoughts, feelings, and desires with His. Simpson encourages believers to open their hearts to receive this transformative power, which enables them to fulfill the righteousness of the law not by their own efforts but through Christ living in them.
