It all begins with a decision. A decision to “let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven” (Matthew 5:16). You get to a point where you realize that life should not be about you, but about how you can contribute to the larger society. Christianity is defined by selflessness and it is “unchristian” to focus exclusively on your personal concerns without sparing a thought for your world. Working as the salt and light of your world is not a function of your income or resources. It is a decision to respond to the words of Jesus.
Your higher life in Christ begins when you make that switch from trying to use God to get what you want and focus on the betterment of your world instead. Beyond the four walls of the church, there are a lot of positive differences you can make in the economy, culture, and government. You should focus on how you can wield an influence over the economy of your world. The trick is to make a decision that you want to do so. You have to take responsibility for the economy of your world before you can seek productivity at that level. You will receive grace, wisdom and power for performance after you take responsibility.
Tony Elumelu lights up his world when he facilitates training, mentorship and $5,000 startup capital for thousands of African Entrepreneurs every year (since 2015). It would be naive to think he is doing this because he has no personal ventures of his own or personal problems. You do not have to start with your country or $5,000 per recipient. It could be as simple as setting aside a tithe of your time to work for people that cannot afford your professional fee. There is never going to be a day when you will not have personal problems of your own. You have to make the switch from focusing on your personal problems to focusing on your duty to light up the economy of your world.
