Why is belief in God important for salvation?

The necessity of belief for salvation is a foundational doctrine within the Reformed tradition, affirmed by passages such as John 3:16 which states, 'For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.' In the sermon, the fate of the lord who doubted Elisha's prophecy serves as a poignant illustration that unbelief leads to spiritual death. The lepers' decision to venture into the camp of the Assyrians symbolizes the act of faith—recognizing their dire situation and taking the risk of leaning on God's promise of mercy. Ultimately, faith in God's provision through Christ is the pathway to salvation, whereas disbelief results in separation from His grace.
