We are created with different ability. We have something special in us that God want us to use for the lifting, edification and glorification of God and helping people around us.
We have different gifts that God want us to use to promote the kingdom and for the growth of the church.
We need to always use what we have to help others and to do God's work.
There is always reasons why God do things and that is the same reasons God did not give all gifts to one man so that we can be useful
