Jessie Penn-Lewis emphasizes the transformative power of the Cross in reshaping our perspective and actions, urging believers to view themselves and others through the lens of Christ's love rather than through a carnal viewpoint. She highlights that true identification with Christ involves a continual reliance on Him as our source of action, leading to a life marked by humility and dependence on God. By yielding the 'I' to the Cross, believers can experience a profound change in their speech and behavior, moving away from self-centeredness to a life that reflects God's will. Penn-Lewis calls for a deeper commitment to allow the Holy Spirit to guide our words and actions, fostering a community that speaks with purpose and clarity. Ultimately, she challenges us to embrace the crucifixion of the self to allow Christ to be the new center of our lives.
