How do we know that prayer is necessary for salvation?

According to the sermon, while salvation is by grace alone, prayer is defined as an indispensable action for obtaining that grace. J.C. Ryle argues that 'no man and no woman can ever expect to be saved who does not pray.' This assertion is rooted in the biblical understanding that faith, which is vital for salvation, naturally expresses itself in prayer. Without the act of reaching out to God through prayer, one cannot manifest a sincere desire for repentance and relationship with Him. Therefore, prayer is not merely an optional practice but a critical act of seeking God's mercy, which aligns with passages indicating the necessity of engaging with God (Romans 10:13).
