God wants you to be holy, so he is going to set you on a path of purification if you choose to do his will. He is the one who is going to make you holy. This process is going to strip away many things you hold dear. It’s going to require active participation in his will, doing what is right and good. But it’s also going to require passive acceptance of things that are out of your control. See everything you do and experience as a chance to grow in holiness, and God will make you into a saint.
