He doesn’t call the qualified, but He qualifies the called.
This gives me hope, and I’m sure it will give you hope too.
We may not be educated, or have the best communicating skills. We may not have the best literacy, or even have much charisma. But God made us. He made us to worship Him, and to reach others, so that they may come to know Him too.
So long as we commit ourselves to Him, He will use us in ways that we can never prepare for.
So don’t wait to be highly educated, or to have great literacy skills, to be an excellent communicator, or to have a personable character. Because God can use you now. In the state that you are in, and with any limitations you think you have, God can use you.
He uses the sick to reach the ailing, the broken to meet the wretched, and the poor to help those who lack. Whatever situation you are in, God can use your lowly state to appeal to those in a likewise destitution.
For when God calls you, He qualifies you.
