Why is it important to control our tongue in Christianity?

The importance of controlling our tongue is emphasized throughout the book of James, particularly in James 3 where it is described as a small but powerful member of our body. The tongue can bless or curse, and it reflects what is in the heart, as Jesus pointed out in Matthew 12:34-35. If our hearts are genuinely transformed by God's grace, our speech will naturally reflect that change, producing encouragement and truth rather than deceit and harm.

A failure to control our tongue often indicates a deeper issue of the heart—pride and arrogance, which leads to a religion that is ultimately vain and deceptive. In contrast, a restrained tongue is a mark of true religion, evidencing humility and a heart aligned with God’s will. Thus, the act of controlling our speech is not merely about discipline but reveals the transformative work of God within us, affirming our identity as children of God.
