F.B. Meyer emphasizes that true fulfillment comes from being filled with Christ, who is the source of all fullness for both the Church and individual believers. He illustrates how earthly pursuits and human love often leave us wanting, while only in Christ can we find complete satisfaction and grace. Meyer encourages believers to actively receive this fullness through faith, worship, gratitude, and mutual submission, highlighting that Christ's infinite nature ensures we can never exhaust His love and power. He reminds us that this fullness was made available through Christ's death and resurrection, and that our growth in faith should reflect the stature of Christ. Ultimately, Meyer calls for a conscious effort to appropriate the blessings of Christ in our lives.

Chuck Smith explores the contrast between life 'under the sun' and life 'in the Son,' emphasizing that life on the human plane is filled with frustration, unfulfilled desires, and a sense of futility. He illustrates how pursuits for happiness, possessions, and wisdom ultimately lead to bitterness and emptiness. In contrast, life in the Son offers fulfillment, purpose, and spiritual richness, resulting in love, joy, and peace. Smith challenges the congregation to reflect on their choices regarding which plane they live on, urging them to embrace the truth of life in Christ rather than the lies of the world.

Thomas Brooks emphasizes that a suffering Christ is the ultimate source of fulfillment and satisfaction for Christians, encapsulating all the perfections and needs of humanity. He illustrates that Christ embodies everything believers require—nourishment, protection, guidance, and healing—making Him indispensable for both spiritual and temporal needs. Brooks argues that the worth of Christ surpasses all earthly treasures, and in Him, believers find complete satisfaction and joy. He challenges Christians to recognize the sufficiency of Christ in their lives, highlighting that nothing more is needed for holiness and happiness.
