John Piper, a well-known Reformed theologian and pastor, has expressed concerns and criticisms regarding certain aspects of what is often termed “Free Grace Theology.” While his opposition is not directed at the concept of salvation by grace through faith, his views on specific nuances of Free Grace Theology stem from his broader Reformed theological framework.

One of the key areas of contention is the nature of saving faith and its relationship to good works. Piper emphasizes the concept of “Christian hedonism,” which asserts that the ultimate purpose of human existence is to glorify God by finding joy and satisfaction in Him. In this context, Piper argues that genuine saving faith will inevitably lead to a transformed life characterized by good works and obedience as a natural outpouring of that faith.

Piper also stresses the importance of the doctrine of justification and sanctification working in tandem. He is cautious of any interpretation of grace that might divorce the concept of grace from the transformative process of sanctification, believing that true saving faith will result in a life marked by ongoing spiritual growth and pursuit of holiness.

Furthermore, Piper’s Reformed perspective emphasizes God’s sovereignty in salvation and a robust understanding of God’s glory. While Free Grace Theology might be seen by some as focusing primarily on the individual’s assurance of salvation, Piper’s concerns lie in ensuring that God’s glory and the comprehensive nature of the gospel message are upheld.

It’s important to note that Piper’s critiques are within the context of his own theological framework and are not a wholesale rejection of grace-based salvation. They represent his desire to emphasize the transformative power of God’s grace and the holistic implications of the gospel on the believer’s life.
