The answer is: In secret

Matt 6:1-18 - Not like the Pharisees who made sure everyone knew what good works they were doing

The Gospel of Matthew often emphasizes inward spirituality over outward displays of righteousness. When Jesus talks about doing charitable works, praying, and fasting "in secret," he’s calling us to a more authentic relationship with God, one that isn’t seeking human applause. In Matthew 6:1-18, Jesus compares true devotion to a hidden treasure, where the real glory lies in private communion rather than public acclaim.

The idea of "doing good in secret" hearkens back to several sections of the Hebrew scriptures. In Proverbs, for instance, it is noted, “He who is kind to the poor lends to the Lord,” which frames charitable actions as not just good deeds, but a spiritual investment. It's perhaps intriguing to think about the concept of charity being linked to divine worth rather than social currency!

When the topic turns to prayer, many recall the scripture encouraging spaciousness in prayer — perhaps the connection here is reminiscent of figures such as Hannah in the book of 1 Samuel praying silently in the temple. Fasting, often accompanied by deeper reflections, calls to mind stories like Moses, who fasted to seek God's guidance when the Israelites strayed. In each of these cases, there’s an echo of personal sincerity, transforming the act into a sacred dialogue rather than a performing art for the audience.

Thus, engaging in charity, prayer, and fasting not for the spectacle, but genuinely grows our spiritual roots, deepening our understanding and empathy towards others — a true hallmark of personal faith.
