C.H. Spurgeon emphasizes that serving the Lord should be a joyful experience, as true service comes from a heart filled with gladness rather than obligation. He argues that God desires cheerful servants who express their love through joyful obedience, contrasting this with the idea of serving out of sadness or reluctance, which is not genuine service. Spurgeon illustrates that just as soldiers who fight for their country do so with enthusiasm, Christians should approach their service to God with a joyful spirit, as this reflects their sincerity and acceptance. He encourages believers to demonstrate their joy in serving God to the world, showcasing that true religion is a source of delight rather than slavery. Ultimately, he calls for a heart of gladness in our service, as it strengthens and uplifts our spirits.

Shane Idleman explores the essence of worship, contrasting three types: cemetery, circus, and Christ-centered. He emphasizes that true worship is not merely about music or style but is a heartfelt expression of reverence and obedience to God. Idleman argues that worship should be a lifestyle, reflecting our relationship with Christ, and challenges the congregation to examine their hearts and motivations in worship. He highlights the importance of worship as a communal and personal act that should be filled with expectancy and authenticity, rather than mere tradition or preference. Ultimately, he calls for a return to Christ-centered worship that honors God and transforms lives.

A.W. Tozer emphasizes the mystical and spiritual essence of New Testament faith, urging believers to let their worshiping hearts guide their theological understanding. He asserts that a heart filled with love for God can intuitively grasp truths that transcend intellectual comprehension. Tozer argues that the real theological conflict today lies not between fundamentalism and liberalism, but in recognizing the deeper spiritual truths that can only be discerned through a heart illuminated by the Spirit. He calls for a return to a heart-centered approach to faith that prioritizes spiritual insight over mere intellectual debate.
