I feel like as Christians it's important to be modest in the way we dress because our bodies are the temple of the Holy Ghost and we should respect Him and ourselves.
As christian women we should not want to reveal our body to anyone except our husbands. Men and women are made differently, in that, men struggle with lust on a regular basis and women cannot understand that. We shouldn't tempt our fellow christian brothers in Christ by revealing our body to them. It's important to cover your thighs as the Bible refers to the thigh as "nakedness".
Exodus 28:42 And thou shalt make them linen breeches to cover their nakedness; from the loins even unto the thighs they shall reach:
And I beleive women should wear dresses or skirts below the knee because it is less revealing of your figure than pants. I want my body to be for my husband and noone else. I don't wish to draw attention to myself. Here is the Bible verse for this personal conviction.
Deuteronomy 22:5 The woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment: for all that do so are abomination unto the LORD thy God.
I don't want to be a stumbling block for those around me. Tempting men to look at my body is wrong and causing them to have lustful thoughts. Especially in God's house we need to remember the reason we go to church and be very careful how much skin is revealed. It can be difficult to focus on Him if your showing cleavage or your skirt is too short.
Romans 14:13 Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.
Matthew 5:28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
And because we have 4 boys we are more aware than ever of how important modesty can be. We don't want our boys growing up seeing half naked women and girls walking around. We want to guard their hearts as long as possible and try to keep their minds pure and free of impure thoughts. It might sound impossible but we believe it can be done by keeping them in church at teaching them the importance of keeping their bodies sacred and pure for their spouse.
I know it won't be easy and some critics may say we're crazy for "sheltering" them but we are doing our best to "train them up in the way they should go."
