C.H. Spurgeon, in his sermon 'Limiting God,' emphasizes the tendency of humanity to restrict God's power and grace through dictation, distrust, and despair. He highlights how people often prioritize sins against others over their offenses against God, failing to recognize the gravity of unbelief and lack of love for the Creator. Spurgeon urges believers to abandon their limitations on God's sovereignty, reminding them that God's ways and timing are beyond human understanding. He calls both saints and sinners to trust in God's boundless mercy and to persist in prayer, regardless of circumstances. Ultimately, he encourages all to embrace God's infinite love and grace, asserting that no one is beyond the reach of His salvation.

This sermon emphasizes the importance of believing in God's great promises and the consequences of unbelief, focusing on the covenant, holiness, fearlessness, and courage of those who trust in God's salvation. It warns against despising God's promises and the dangers of influencing others negatively with doubt and unbelief.

John Piper preaches about God's purpose in leading His people through the wilderness, emphasizing the lessons of humility, dependence, and trust that are learned in the midst of trials and detours. He highlights how the wilderness serves as a testing ground to prevent self-sufficiency and pride, ultimately leading to a deeper reliance on God's provision and power. Through the example of the Israelites' journey, Piper illustrates the importance of embracing the wilderness experiences in life as opportunities for growth, gratitude, and obedience to God's leading.
