Why is preaching to the unconverted important for Christians?

Preaching to the unconverted is crucial for demonstrating the love and mercy of God, as well as the urgent call for repentance. The biblical mandate for Christians is to declare the Gospel, which includes a call for sinners to turn from their sins and embrace Jesus as Lord and Savior. Acts 3:19 exhorts, 'Repent therefore, and turn back, that your sins may be blotted out.' Engaging with unconverted individuals allows the minister to be an instrument of God's grace, calling them to consider the weight of their eternal state. Moreover, the examples of Jesus and the apostles show that exhortation to repentance and faith is consistent with the gospel message, which invites the spiritually dead to experience the life-giving power of Christ.
