The sermon, drawn from Zechariah 7–8, confronts the tension between religious ritual and genuine relationship with God, using the post-exilic Jews’ question about continuing fasts as a springboard. It reveals that God’s concern is not with external observances like the fasts of Tisha B'Av, but with the heart behind them—whether they stem from self-righteousness or true repentance and love. The passage exposes the danger of empty traditions, showing how self-imposed religious practices can become substitutes for authentic worship when the heart is hardened, as seen in the ancestors’ refusal to heed the prophets. In contrast, God’s response in Zechariah 8 offers a vision of future restoration: Jerusalem as the city of truth, peace, and divine presence, where even the poor and elderly will dwell in safety, and nations will come to seek the Lord. The message culminates in a call to live righteously not out of legalistic obligation, but out of a heart transformed by God’s grace, with all actions—rituals, traditions, and daily life—done to the glory of God, as affirmed in 1 Corinthians 10:31.
