He illustrates how true joy comes from a deep, inner source that remains unaffected by external circumstances, allowing believers to face trials and temptations with strength and gladness. Simpson encourages Christians to embrace this joy as a vital part of their faith, asserting that it empowers them in service, testimony, and daily life. He concludes that this joy is rooted in the assurance of salvation, the Holy Spirit, and the indwelling presence of Christ, which together sustain a believer's joy amidst life's challenges.

F.B. Meyer emphasizes that true strength comes from the joy of the Lord, contrasting it with the fleeting joy of the world that masks deeper sorrow. He explains that a joyful heart is vital for effective living, as it energizes and motivates us to serve others selflessly. This divine joy is rooted in the assurance of God's forgiveness and flourishes even in trials, independent of external circumstances. Meyer encourages believers to seek joy in God Himself, which naturally overflows to uplift others and spread hope. Ultimately, the joy of the Lord not only strengthens us but also becomes a source of light for those around us.

Chuck Smith emphasizes the profound joy found in the Lord, contrasting it with a historical view of spirituality that equated holiness with sadness. He highlights that true joy comes from knowing our sins are forgiven and walking with Jesus, who offers a fullness of joy through fellowship and prayer. This joy not only strengthens us in difficult times but also serves as a powerful witness to others, drawing them towards the happiness that comes from a relationship with God. Smith encourages believers to recognize that the joy of the Lord is both attractive and contagious, capable of uplifting those around us.
