Elijah McCoy (1843-1929) invented a device, initially built for trains, which enabled machinery to be lubricated while in operation. The accomplishment was of a much greater magnitude because McCoy was an African American living in a racially intolerant era. Others later built their own versions of the device, but none could compare with the original. When buyers recognized this, they insisted on buying nothing other than the "real McCoy." You have probably  heard it before, but did you know that the truth behind this phrase appeared first in the Bible? In his first epistle, the apostle John wrote of some who were in the church but were not true believers. He wrote: but they went out, that they might be made manifest that they were not all of us. (1 John 2:19) Dear reader, how about you? I hope that, as far as a Christian testimony is concerned, those who know you consider you "the real McCoy."
