Woman, it is good that what you do to see yourself beautiful physically, is not something that occupies all the space of your heart, since that would become vanity, and would make you weaker and withdrawn from the Lord. That is why it is good to keep your heart before the Lord.
Everything you do, let it be for the glory of God, for the enjoyment of your husband, but if you are not married, be careful not to lead others to temptation, but do what you are going to do thinking about doing it for the glory of God.
In the first epistle of Peter we find a great teaching of that apostle for women. Peter exhorts women to focus not on external appearance, but on their heart, which is full of the grace of God, of the Holy Spirit, to have the grace of God, which is the greatest beauty that a woman can have.
3 Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel;
4 But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price.
1 Peter 3:3-4 (KJV)
The advice here is that the main thing that stands out in women not be the outside, not those great hairstyles, not those expensive dresses or luxurious clothes, but that what can make a woman stand out be a pure and pleasant heart in front of God.
Women, beware of everything in vain, of the vanity of life, love the Lord with all your heart, keep His word, and try when someone talks about you, that they do not talk for your beauty, but for the beauty of your heart and the grace of God will cover you every day, it will beautify your life forever.
