We all have blind spots—areas of our lives that need to be uncovered so we can see correctly and adjust our lives accordingly. But they are hard to identify.

I can think of at least one glaring blind spot in American Christian history. Slavery. How could Christians who supposedly believed the gospel so easily rationalize the enslavement of other human beings? Churchgoers with good intentions worshiping God together every Sunday and reading the Bible religiously all week long, all the while using God's Word to justify treating men, women, and children as property to be used or abused.

Not long ago, God began uncovering a blind spot in my life. An area of disobedience. A reality in God's Word that I had pretended did not exist.

Today more than a billion people in the world live and die in desperate poverty. They attempt to survive on less than a dollar per day. Close to two billion others live on less than two dollars per day …. Anyone wanting to proclaim the glory of Christ to the ends of the earth must consider not only how to declare the gospel verbally but also how to demonstrate the gospel visibly in a world where so many are urgently hungry.

What is the difference between someone who willfully indulges in sexual pleasures while ignoring the Bible on moral purity and someone who willfully indulges in the selfish pursuit of more and more material possessions while ignoring the Bible on caring for the poor? The difference is that one involves a social taboo in the church and the other involves the social norm in the church.

We look back on slave-owning churchgoers of 150 years ago and ask, "How could they have treated their fellow human beings that way?" I wonder if followers of Christ 150 years from now will look back at Christians in America today and ask, "How could they live in such big houses? How could they drive such nice cars and wear such nice clothes? How could they live in such affluence while thousands of children were dying because they didn't have food or water? How could they go on with their lives as though the billions of poor didn't even exist?"

Is materialism a blind spot in your Christianity today? Surely this is something we must uncover, for if our lives do not reflect radical compassion for the poor, there is reason to question just how effective we will be in declaring the glory of Christ to the ends of the earth.
