What does 'never despise the day of small things' mean in Christianity?

The phrase 'never despise the day of small things' taken from Zechariah 4:10 encapsulates a profound truth in Christian faith: God often works through the seemingly insignificant. The parable of the mustard seed exemplifies this principle, illustrating how the church began with a mere handful of believers yet grew to encompass millions. This teaches us that God's plans often use unlikely circumstances and people, urging us not to overlook minor beginnings. Each small act of faith can be the foundation for much greater works, aligning with the biblical narrative of God’s redemptive history from small beginnings that yield extraordinary outcomes.
