Do you feel like you aren’t enough? That’s good–because you aren’t. The amazing thing about God is that it doesn’t matter. He said He could even make a rock cry out; He used a donkey to speak in the past. How much more can He use a person who isn’t enough? He’ll fill you up to the point that you overflow, so that you can do His will.
Don’t be upset that you’re not enough. Don’t give up because of that–He wants to use you in spite of that so that all the glory goes to Him.
