How do we know that modesty is important for Christians?

Modesty is significant for Christians as it embodies a humble heart posture before God. 1 Timothy 2:9 and 1 Peter 3:3-4 highlight that true beauty comes from within, specifically from a meek and quiet spirit, esteemed by God. Modesty in dress should be a physical manifestation of an inner desire to honor God in worship, without drawing attention to oneself. When the focus shifts from God's glory to our appearance, it distracts from true worship, which is about recognizing our need for Him.
