The Apostle Paul emphasized that the gospel team spared no effort to preach the gospel to the Corinthians as Christ’s ambassadors. It is his prayer and earnest hope that the Word will find fertile ground in their hearts. It is his desire that the Corinthians would be established in the faith. The fruitful heart is good ground, good soil. The heart is basically sinful. The heart that is sanctified by God’s grace, produces fruit.
