Every person conceived and born after the Fall is a sinner. Every person who believes in Jesus Christ as their Lord and Savior is a saint. Clothing, which is significant in Scripture, speaks to both of these identities.
After the Fall, a loving God provided Adam and Eve with two kinds of clothing. Coats of animal skins covered their physical body, but the covering of Jesus Christ was promised for their spiritual body. As forgiven sinners, we are clothed in the garment of salvation which is the robe of righteousness given freely to us by Jesus Christ (Isa. 61:10). Wearing the robe of His Son, God sees us as holy. However, it is a consequence of the fallen world that men and women see each other through sin-tainted eyes. For this reason, God tells women to dress modestly—in a way that professes faith—so that they do not tempt an admiring man by way of false glory to sinful thoughts or deeds.
Adam and Eve covered only certain parts of themselves with fig leaves, but God designed clothes to cover their bodies. From this we know that Adam and Eve could not sufficiently cover themselves physically (nakedness) or spiritually (works righteousness). The work of their hands was neither acceptable nor enough. There was absolute necessity for the full covering and righteousness of the Savior, Jesus Christ. Today, whenever we consider clothing, we can remember that its purpose is to cover our bodies and protect us from our own corrupted thoughts.
Here is where instruction in purity does what sex education does not. Clothing is not usually considered very significant in sex or sexuality education. But to help male and female of any age understand that we are called to a lifestyle of purity means that we must talk about clothing.
