The fact that Jesus can use even a donkey to accomplish his purpose should also encourage us when we feel unworthy & unusable. He loves you!
Andrew, Peter, and others joined Jesus from non-churchy professions. If he can use them, then just imagine what he can do with you!
I don’t know about you, but it’s a huge relief to me to know that God wants to use my life, flawed as it is, for his glory. Be open to him.
Do you ever doubt whether God can use you? Some of the biggest champions in the Bible came from humble &/or rough circumstances.
