Until Adam and Eve sinned they were unaware of their nudity (Gen 2:25, 3:7). Both genders should dress appropriately, as the sexual realm is
area of temptation (1 Tim 2:9,10). We are not to draw our attention to our bodies, by the type or lack of clothing we wear for as Christians our bodies belong to God and are to be used for His glory, not our own (Rom 12:1). The Bible instructs us to live in such a way as not to put any stumbling block in another's path (Rom 14:13,20,21; 1 Cor 8:9).
We should not ‘advertise’ the good-works we do, instead letting the actions speak for themselves (Mt 6:1-8,16-18). We should also be modest in how we view ourselves – not thinking of ourselves too highly (or too lowly either), rather with a balanced view, giving God credit for what He has done in us (Rom 12:3).
