Holiness (to be like Jesus) is a lifetime endeavor for every person in every vocation. Don’t worry if you don’t see yourself as very holy right now. God will form you slowly, day by day and week by week, so that you will be ready to be His instrument when the time comes. But for now, use the sacrament of Penance at least once a month. Repent of your sins, receive the sacraments, and pray every day. You will be surprised at how Christ-like you can become!
