If I am asked to be holy, it seems to be a tall order. Where and how do I start? There must be a whole list of things for me to do.
Here's the good news. Try to become pure, and you will be holy as well. Ask the Holy Spirit to make your heart pure, then your thoughts, words, and actions will automatically come out pure. When you are pure, your are clean, and you'll have peace in your heart and be fragrant before the Lord. So, be pure and let the Lord love you.
