One of the conditions of living in a fallen world that is beset by sin is that, even though we live in a world of abundance, the way so much of the world functions, including our economic system, assumes scarcity. This makes it really hard, even for Christians, to live lives of generosity. One of the keys to change our mindset of scarcity into a mindset of abundance is to practice gratitude. When we shift from complaining about what we don’t have or coveting what others have, to thanking God for what He has given us, our perspective about the world starts to change, and it becomes easier to believe that we indeed live in a world of abundance and that we can be generous.
