We live in a celebrity-obsessed culture so perhaps that is where the desire to stay young looking comes from. As Christians, we know that real beauty comes from within, the beauty and confidence that comes from knowing that you are a child of God, made in God's image and likeness. Our inherent self-worth comes from knowing we have value because we are created by God and called to be in relationship with the Divine. We are baptized into the life of the Trinity, how awesome is that! It's a shame so few people realize that reality and are convinced of it.
I think it's important that we get that message out.....especially to young people.
