According to the World Bank, the average per capita income worldwide currently is $10,298. If you make more than that per year (and have a refrigerator!), you are in the top 1% of wealthy people in the world. I suspect that includes many of us. 
The United States is 19th in the world’s top per capita rankings. Cuba is 128th. I have been to Cuba for missions work and have observed how the people there are rich, indeed, though you may not see it on the surface. In Cuba I’ve seen a great deal of focus on and hope in the wealth that Christians have stored up in heaven. Earthly riches are not so important. At a church in the province of Pinar del Rio, I marveled that most of the young adults were involved in the church’s ministry work, in the Bible Institute, or in running their own house churches. They had set their minds on things above. 
Let’s be generous but also keep the uncertain riches of today from consuming us. Let’s set our hearts on the unseen treasures in heaven where our true hope, Jesus, awaits us.
