Modesty could be called humility because by definition modesty is holding to an unassuming or moderate belief in the estimation of one’s own abilities or achievements; thereby trusting in God’s grace.
It is also showing moderation in one’s own behavior like being free from vanity, egotism, boastfulness, or great pretensions. Appearance and actions reflect the life we live. We present ourselves to the world based on our self-perception and aspirations. To be modest is to consider what our clothing and behavior represent and how they influence those around us.
“Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things people look at. People look at the outward appearance, but the LORD looks at the heart.” 1 Samuel 16:7
Modesty is the outward expression of inner purity.
1 Timothy 2:9-10
“likewise also that women should adorn themselves in respectable apparel, with modesty and self-control, with what is proper for women who profess godliness—with good works.”
Although all people of all ages should be clothed with humility toward one another, knowledge of who we are in Christ is crucial to a life of biblical modesty.
“I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, eager to maintain the unity of the Spirit in the bond of peace.” Ephesians 4:1-3
Modesty certainly includes gentleness, patience, bearing with one another, and having a spirit of unity and living in peace among others. This modest type of behavior pleases God and it also makes others see Christ living in us and may cause others to look to the Savior.
