“His master replied, ‘Well done, good and faithful servant! You have been faithful with a few things; I will put you in charge of many things. Come and share your master’s happiness!’ ” Matthew 25:21
Although faith and Christianity are of the heart, it often behooves us to think about them logically. As Christians, we often ask ourselves many questions regarding our situation, and the situation of others. Why has God not blessed me with a son? Why can I never get rich? Why can I never lose all of this weight? These are not bad questions, but I urge you to think about these same questions in another light. What have I done to deserve such a wonderful daughter? Why has God chosen to bless me with a job that allows me to feed my family? Why has God never chosen to give me cancer? 
It seems silly to question why bad things have not happened to us, but that level of reasoning is an important step to realizing why God blesses us when He does. God often blesses us incrementally. When we show consistent generosity, He blesses us with children, jobs, and health. Everything is on a scale, though, including our own generosity. In Matthew 25:21, we are being shown that small faith is rewarded with small blessings, medium faith is rewarded with medium blessings, and a grand faith and generosity over many years is rewarded with vast riches and abundance beyond our wildest dreams. God is comfortable granting us these miraculous blessings since He has now seen our generosity that has been shown steadily and bountifully. As you increase your giving, and lengthen your track record of benevolence, God will reward you, but not directly. Watch for signs, and remember that he who knows how to give freely will certainly learn how to receive freely as well.
