I strongly believe that God picks people who are destined to carry out His mission, even if they have not their purpose. The gifts the we have may be completely to others, but it indeed shows that He created us uniquely, in which through Him, we are able to discover that gift. Some are born with it naturally, but for others, I think that He shapes us first or molds us into what we are destined to do, and only then once we are fully matured in our spiritual journey, He will reveal that road for us. It doesn’t matter whether you are poor or rich, and we should not have perspective on others regarding to our flesh.
