This quote emphasizes that true salvation cannot come from within ourselves or through a gradual process of self-improvement. C.H. Spurgeon argues that human nature, being inherently sinful, cannot evolve into something good on its own. Instead, he asserts that salvation is a divine gift from God, achieved through Jesus Christ. This act is supernatural, meaning it transcends human ability and understanding. Spurgeon highlights that no matter how lost or weak a person may feel in their sins, they can still receive this gift. The core message is about the necessity of divine intervention for true transformation, which brings freedom from sin and a new mindset in life. Ultimately, it reminds us that spiritual growth relies not on our efforts but on the power of God.
