A.W. Tozer emphasizes the vital role of courage in prayer, asserting that just as bravery is essential in the world, it is equally crucial in the kingdom of God. He encourages believers to approach God with unwavering faith and boldness, believing in His love and goodness. Tozer insists that successful prayer is unconditional and must be offered with the understanding that God will always act for our benefit. He reassures that prayers made with such courage and trust cannot go unanswered, as they align with God's character and promises. Ultimately, he reminds us of God's infinite lovingkindness, urging us to trust Him completely.

David Wilkerson emphasizes that God desires His people to serve Him with joy and gladness, rooted in the understanding of His tender love and ongoing work in their lives. He warns that a lack of joy in serving can lead to spiritual emptiness and vulnerability to life's challenges, as illustrated by Moses' warning to Israel. Wilkerson encourages believers to rejoice in what God has done and to maintain a spirit of gladness regardless of circumstances, citing various Psalms that call for joy and gladness in the Lord. He asserts that true joy is not dependent on external factors but is a constant state that flows from trusting in God's love and truth. Ultimately, he calls for a life filled with gladness that serves as a testimony to others.
