Why is it important for Christians to testify about God's grace?

Testifying about God's grace is crucial for Christians because it encapsulates the essence of the Gospel that proclaims salvation through faith alone, by grace alone, in Christ alone. This proclamation nurtures the faith of believers and attracts others to the truth of the Gospel. According to Acts 20:27, Paul emphasized not shunning to declare all the counsel of God, which inherently includes His grace towards undeserving sinners. Such testimonies not only build the Church up in faith, but they also protect it from false teachings that seek to distort the gospel. By sharing the message of grace, believers reinforce their identity in Christ and the transformative power of His redemptive work.
