We must trust in God to do all things for us. Going back into history, who would have known that Communism would collapse one day? It did happen (the Blessed Mother actually predicted the birth of Communism and its eventual collapse when she appeared at Fatima in 1917). Something like turning a whole country around away from corruption and hypocrisy seems like an almost impossible task, but if we pray hard and remain faithful, God will deliver what we ask for in time. Therefore, rely upon the Lord to accomplish all things for us, large and small.
