The Sermon on the Mount is addressing the issue of authenticity. Just how genuine is our relationship with the Lord Jesus? It is altogether possible to practice an outward display of piety—to “talk the talk”—without demonstrating any inner reality of godliness. This is true of every professing Christian, and it is especially true of those engaged in Christian ministry. Authentic Christianity requires an outward and discernible “work of faith” (1 Thess. 1:3; 2 Thess. 1:11). But it also requires genuine godly affections and an inner discipline of the heart.

According to Jesus, it is what we do in secret that matters most. Jesus is not suggesting that the outward is unimportant—far from it. “What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him?” (James 2:14).

The answer is emphatically no. Still, it is also possible to have outward works but no inner reality. In this instance, religion is a pretense. Six times in the Sermon on the Mount, alluding to three distinct exercises, Jesus employs the term secret:

• Give “in secret…and your Father who sees in secret will reward you” (Matt. 6:4).
• Pray “in secret…and your Father who sees in secret will reward you” (v. 6).
• Fast “in secret…and your Father who sees in secret will reward you” (v. 18).

There is a manner of ministry that is more about self-service than self-sacrifice, self-indulgence than self-discipline, and self-promotion than self-denial. There is also giving that is designed for recognition—plaques on walls intended to be read by generations to come, or press releases informing the world of “generous donations”; prayers in pristine Cranmerlike language of the sixteenth century suggesting depths of personal piety; fasting that is shown via open-necked T-shirts revealing a ribbed torso.

But all these outward demonstrations of piety may be no more than mere hypocrisy. The Greek word translated “hypocrites” (Matt. 6:2, 5) refers to the masks worn by ancient actors as symbols of pretense and show. Thus, give with fanfare; pray with pride; fast with notice. This ministry is inauthentic. It is a sham.
