Why is the heart important in the gospel ministry?

The text emphasizes that true participation in gospel ministry stems from a willing heart. Exodus 35:21-22 highlights how the Israelites brought their offerings based on a willingness stirred by the Spirit of God. This reinforces the idea that external actions alone cannot fulfill God’s requirements; a transformed heart is necessary. Additionally, Jeremiah 17:9 warns us about the deceitful nature of the heart, showcasing that only God can truly change it. Thus, the heart's condition is vital because it determines the genuineness of our service and devotion in the gospel ministry.
