St. Paul reminds us in his First Letter to the Thessalonians that it is the will of God that we are to be holy. If it is God's will, should it not be our will as well? In fact, this is everyone's first and ultimate vocation: to be holy. Why is this so? The purpose of our existence is clear again from St. Paul in his Letter to the Ephesians.  God has willed that we be his adopted sons and daughters, sharing his own Divine Life, so that we may be with him eternally, praising his glory. God created us for this purpose, to be holy, which is what sharing in his life really means. Someone has said that the saddest moment in one's life is not to be a saint when death occurs. What does this mean? It means that if we are not sharing in God's Divine Life when we die, we have failed the purpose of our existence. Holiness is not an option but a command and a just expectation, not for a few canonized persons, but for each of us. It is the will of God.
