The only way to create sustainable change in the world is to change the hearts of the people in the world. For this reason, Jesus is the only sustainable solution to the world's problems.
We cannot create truly sustainable change. Jesus is the only one who can. We shouldn’t tell ourselves that we’re going to “go change the world”, because we cannot change the hearts of the people in the world. Jesus is the only One who can do that. He may use us, but He is the only One who truly “changes the world.” So, Jesus is the ultimate thing that we should be sharing with the world, because Jesus is the only sustainable solution to the world’s problems. We can feed villages, dig wells, give people microfinance loans, offer training so they can take care of themselves, but these are only short-term solutions to the world’s problems. All these things will crumble in the long run due to the essence of human nature – we are self-serving and prideful at our core. Corrupt people, groups, or governments will steal the food supply, limit access to the wells, take over the businesses, and take people’s money. Jesus is the only thing that will change people’s hearts so that these physical things have a lasting impact. I totally believe that these physical things are important, and often times they open the door to spiritual things. But this is my point: Spiritual ministry is the key to sustainable physical ministry.
