You speak of doing good to the world. Is the world such a small thing? And who are you, pray, to do good to the world? First realise God, see Him by means of spiritual discipline. If He imparts power you can do good to others; otherwise not.
You see, women have been essential to every great move of God. Yes, Moses led the Isaelites out of Egypt, but only after his mother risked her life to save him! Closer to our time, Clara Barton was instrumental in starting the Red Cross. Harriet Beecher Stowe's Uncle Tom's Cabin put fire into people's heart to end slavery in the United States. Rosa Parks kicked the Civil Rights movement into gear with her quiet act of courage. Eunice Kennedy Shriver created the Special Olympics. Mother Teresa inspired the world by bringing love to countless thought unlovable. And millions of other women quietly change the world every day by bringing the love of God to those around them.
