What does the phrase 'Lord, I believe; help my unbelief' mean?

This phrase, uttered by a man with a possessed son in Mark 9, encapsulates the struggle many believers face in their faith journey. It acknowledges the reality of belief while confronting the presence of doubt. The man's cry is a beautiful example of humility before God, recognizing that true faith is a gift from God and that even the smallest measure of belief is enough for God to work miracles. This reflects the Reformed understanding that salvation and faith are ultimately grounded in God’s grace, affirming that He is sovereign over our capacity to believe.
